Subject: [PATCH 04/90] Make array equal work with masked Dask arrays and add
 tests (#6325)

* Fix issue where the mask of Dask arrays was ignored and improve tests

* Optimize unmasked numpy arrays

* Add whatsnew

* Use dask.array.blockwise for array comparison

* Faster comparison

* Avoid flattening arrays

* Avoid checking points if one coord has bounds and the other does not have them

* Small simplification

* Add test

* Use a separate map and reduce operation to avoid running out of memory on large arrays

* Correct order of checking if array is floating point dtype

Also consider non-floating point arrays equal with withnans=False

Subject: [PATCH 05/90] Handle NetCDF variable length strings (and other VLen
 types) (#6340)

* Initial workaround - if variable is a "str" type then force it to load.
Would be better to force all Variable Length types to be lazy, but can't
ascertain this information from the CFAuxiliaryCoordinateVariable instance.

* Added some TODO comments

* Working solution that checks for VLEN arrays and handles the special
variable length "str" case.

* Formatting updates

* Added size hinting of variable length arrays using CHUNK_CONTROL context manager

* Access netCDF variable `datatype` via `cf_var.cf_data` to avoid Mock failures.

* Make check on cf_var.cf_data.datatype optional as it assumes underlying
storage is netCDF (which for this module is true, but for mock testing
is not)

* Added warning category

* Added unit tests for VLen arrays.

* Use 'safe-access' version of netCDF4.VLType to satisfy coding-standards checker.

* Updates to comments and added _MEAN_VL_ARRAY_LEN as module variable

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Restored accidentally removed comment

* Updated docstring and added docs

* Updated Whats New

* Fixed some typos in docs

* Fixed doctest indent

* Missing imports for doctest

* Rewording of docs

* Missing black lines in doctest

* Update lockfiles with iris-sample-data

* Better URL for variable length types [Review comment]

* Slight rewording of docs and fix some typos [Review comments]

* reworded hinting section

* Typo

+Variable-length datatypes
+-------------------------
+
+The NetCDF4 module provides support for variable-length (or "ragged") data
+types (``VLType``); see
+`Variable-length data types <https://unidata.github.io/netcdf4-python/#variable-length-vlen-data-types>`_
+
+The ``VLType`` allows for storing data where the length of the data in each array element
+can vary. When ``VLType`` arrays are loaded into Iris cubes (or numpy), they are stored
+as an array of ``Object`` types - essentially an array-of-arrays, rather than a single
+multi-dimensional array.
+
+The most likely case to encounter variable-length data types is when an array of
+strings (not characters) are stored in a NetCDF file. As the string length for any
+particular array element can vary the values are stored as an array of ``VLType``.
+
+As each element of a variable-length array is stored as a ``VLType`` containing
+an unknown number of vales, the total size of a variable-length NetCDF array
+cannot be known without first loading the data. This makes it difficult for
+Iris to make an informed decision on whether to the load the data lazily or not.
+The user can aid this decision using *VLType size hinting* described below.
+
+VLType size hinting
+^^^^^^^^^^^^^^^^^^^
+
+If the user has some *a priori* knowledge of the average length of the data in
+variable-length ``VLType``, this can be provided as a hint to Iris via the
+``CHUNK_CONTROL`` context manager and the special ``_vl_hint`` keyword
+targeting the variable, e.g. ``CHUNK_CONTROL.set("varname", _vl_hint=5)``.
+This allows Iris to make a more informed decision on whether to load the
+data lazily.
+
+For example, consider a netCDF file with an auxiliary coordinate
+``experiment_version`` that is stored as a variable-length string type. By 
+default, Iris will attempt to guess the total array size based on the known
+dimension sizes (``time=150`` in this example) and load the data lazily.
+However, if it is known prior to loading the file that the strings are all no
+longer than 5 characters this information can be passed to the Iris NetCDF
+loader so it can be make a more informed decision on lazy loading:
+
+.. doctest::
+
+    >>> import iris
+    >>> from iris.fileformats.netcdf.loader import CHUNK_CONTROL
+    >>>
+    >>> sample_file = iris.sample_data_path("vlstr_type.nc")
+    >>> cube = iris.load_cube(sample_file)
+    >>> print(cube.coord('experiment_version').has_lazy_points())
+    True
+    >>> with CHUNK_CONTROL.set("expver", _vl_hint=5):
+    ...     cube = iris.load_cube(sample_file)
+    >>> print(cube.coord('experiment_version').has_lazy_points())
+    False

Subject: [PATCH 07/90] Combine cubes 2 (#6334)

* Remove unused 'unique' option from load collections and combine methods.

* Reinstate 'unique=False' in combine merges to fix load().

* Fix typing for combine submodule.

* More typing and other small improvements to combine code.

* Move loading-specific parts from CombineOptions to LoadPolicy.

* Fix LoadPolicy error handling + test.

* Properly support merge_unique, and add equalise_cubes.

* Allow LoadPolicy.context with no settings arg.

* Turn off varying-reference support for 'legacy' load setting only.

* Implement combine_cube as util, and redirect test.

* Small docs fixes.

* Add functioning doctest example for combine_cubes.

* Further doctest fixes.

* Add cubelist combine methods.

* Better documentation of CombineOptions and LoadPolicy settings.

* Recombine LoadPolicy into CombineOptions.

* Fix doctest.

* Rework CombineOptions.set() tests to cover context() method also.

* Add tests for cubelist combine functions (and fix).

* Add tests for individual combine control keywords.

* Added whatsnew, and minimal links in other docs sections.

* Review changes: docs improvements; docstrings for cubelist combine methods.

* Tiny formatting correction.

* Review changes: docs explain not to assign to iris.COMBINE_POLICY.

* Review changes: fix obsolete comments + todos in testcode.

* Review changes: add test for string arg + kwargs.

* Review changes: remove obsolete TODO notes.

 ✨ Features
 ===========
 
+#. `@pp-mo`_ renamed the :class:`iris.LoadPolicy` as :class:`iris.CombineOptions` and
+   :data:`iris.LOAD_POLICY` as :data:`iris.COMBINE_POLICY`, though the original names
+   remain functional (and refer to the same things) for now.
+   (:issue:`6203`, :pull:`6334`)
+
+#. `@pp-mo`_ added new :meth:`~iris.cube.CubeList.combine` and
+   :meth:`~iris.cube.CubeList.combine_cube` methods of a :class:`~iris.cube.CubeList`
+   as an alternative way of accessing the :func:`~iris.util.combine_cubes` mechanism.
+   (:issue:`6203`, :pull:`6334`)
+
+#. `@pp-mo`_ added a new utility function :func:`~iris.util.combine_cubes`, to give
+   general public access to the combine merge/concatenate mechanism introduced for
+   generalised loading support via :class:`iris.LoadPolicy` in the Iris 3.11 release.
+   (:issue:`6203`, :pull:`6334`)
+
+#. `@pp-mo`_ overhauled the :class:`iris.LoadPolicy` facility by adding a new
+   ``equalise_cubes_kwarg`` keyword, enabling it to call the
+   :func:`~iris.util.equalise_cubes` utility function as one of its processing stages.

+    """A control object for Iris loading and cube combination options.
 
-    Options can be set directly, or via :meth:`~iris.LoadPolicy.set`, or changed for
-    the scope of a code block with :meth:`~iris.LoadPolicy.context`.
+    Both the iris loading functions and the "combine_cubes" utility apply a number of
+    possible "cube combination" operations to a list of cubes, in a definite sequence,
+    all of which tend to combine cubes into a smaller number of larger or
+    higher-dimensional cubes.
 
-    .. note ::
+    This object groups various control options for these behaviours, which apply to
+    both the :func:`iris.util.combine_cubes` utility method and the core Iris loading
+    functions "iris.load_xxx".
 
-        The default behaviour will "fix" loading for cases like the time-varying
-        orography case described above.  However, this is not strictly
-        backwards-compatible.  If this causes problems, you can force identical loading
-        behaviour to earlier Iris versions with ``LOAD_POLICY.set("legacy")`` or
-        equivalent.
+    The :class:`CombineOptions` class defines the allowed control options, while a
+    global singleton object :data:`iris.COMBINE_POLICY` holds the current global
+    default settings.
 
-    .. testsetup::
+    The individual configurable options are :
 
-        from iris import LOAD_POLICY
+    * ``equalise_cubes_kwargs`` = (dict or None)
+        Specifies keywords for an :func:`iris.util.equalise_cubes` call, to be applied
+        before any merge/concatenate step.  If ``None``, or empty, no equalisation step
+        is performed.
 
-    Notes
-    -----
-    The individual configurable options are :
+    * ``merge_concat_sequence`` = "m" / "c" / "cm" / "mc"
+        Specifies whether to apply :meth:`~iris.cube.CubeList.merge`, or
+        :meth:`~iris.cube.CubeList.concatenate` operations, or both, in either order.
 
-    * ``support_multiple_references`` = True / False
-        When enabled, the presence of multiple aux-factory reference cubes, which merge
-        to define a extra dimension, will add that dimension to the loaded cubes.
-        This is essential for correct support of time-dependent hybrid coordinates (i.e.
-        aux factories) when loading from fields-based data (e.g. PP or GRIB).
-        For example (notably) time-dependent orography in UM data on hybrid-heights.
+    * ``merge_unique`` = True / False
+        When True, any merge operation will error if its result contains multiple
+        identical cubes.  Otherwise (unique=False), that is a permitted result.
 
-        In addition, when such multiple references are detected, an extra concatenate
-        step is added to the 'merge_concat_sequence' (see below), if none is already
-        configured there.
+        .. Note::
 
-    * ``merge_concat_sequence`` = "m" / "c" / "cm" / "mc"
-        Specifies whether to merge, or concatenate, or both in either order.
-        This is the "combine" operation which is applied to loaded data.
+            By default, in a normal :meth:`~iris.cube.CubeList.merge` operation on a
+            :class:`~iris.cube.CubeList`, ``unique`` defaults to ``True``.
+            For loading operations, however, the default is ``unique=False``, as this
+            produces the intended behaviour when loading with multiple constraints.
 
     * ``repeat_until_unchanged`` = True / False
         When enabled, the configured "combine" operation will be repeated until the
         result is stable (no more cubes are combined).
 
-    Several common sets of options are provided in :data:`~iris.LOAD_POLICY.SETTINGS` :
+    * ``support_multiple_references`` = True / False
+        When enabled, support cases where a hybrid coordinate has multiple reference
+        fields : for example, a UM file which contains a series of fields describing a
+        time-varying orography.
+
+    Alternatively, certain fixed combinations of options can be selected by a
+    "settings" name, one of :data:`CombineOptions.SETTINGS_NAMES` :
 
     *  ``"legacy"``
-        Produces loading behaviour identical to Iris versions < 3.11, i.e. before the
-        varying hybrid references were supported.
+        Apply a plain merge step only, i.e. ``merge_concat_sequence="m"``.
+        Other options are all "off".
+        This produces loading behaviour identical to Iris versions < 3.11, i.e. before
+        the varying hybrid references were supported.
 
     * ``"default"``
         As "legacy" except that ``support_multiple_references=True``.  This differs
         from "legacy" only when multiple mergeable reference fields are encountered,
         in which case incoming cubes are extended into the extra dimension, and a
         concatenate step is added.
+        Since the handling of multiple references affects only loading operations,
+        for the purposes of calls to :func:`~iris.util.combine_cubes`, this setting is
+        *identical* to "legacy".
+
+        .. Warning::
+
+            The ``"default"`` setting **is** the initial default mode.
+
+            This "fixes" loading for cases like the time-varying orography case
+            described.  However, this setting is not strictly
+            backwards-compatible.  If this causes problems, you can force identical
+            loading behaviour to earlier Iris versions (< v3.11) with
+            ``COMBINE_POLICY.set("legacy")`` or equivalent.
 
     * ``"recommended"``
-        Enables multiple reference handling, *and* applies a merge step followed by
-        a concatenate step.
+        In addition to the "merge" step, allow a following "concatenate", i.e.
+        ``merge_concat_sequence="mc"``.
 
     * ``"comprehensive"``
-        Like "recommended", but will also *repeat* the merge+concatenate steps until no
-        further change is produced.
+        As for "recommended", uses ``merge_concat_sequence="mc"``, but now also
+        *repeats* the merge+concatenate steps until no further change is produced,
+        i.e. ``repeat_until_unchanged=True``.
+        Also applies a prior 'equalise_cubes' call, of the form
+        ``equalise_cubes(cubes, apply_all=True)``.

             of matching dimension and scalar coordinates.  This may be supported at
             some later date, but for now is not possible without specific user actions.

+    --------
+    Note: :data:`COMBINE_POLICY` is the global control object, which determines
+    the current default options for loading or :func:`iris.util.combine_cubes` calls.
+    For the latter case, however, control via argument and keywords is also available.
+
+    .. Note::
+
+        The ``iris.COMBINE_POLICY`` can be adjusted by either:
+
+        1. calling ``iris.COMBINE_POLICY.set(<something>)``, or
+        2. using ``with COMBINE_POLICY.context(<something>): ...``, or
+        3. assigning a property ``COMBINE_POLICY.<option> = <value>``, such as
+           ``COMBINE_POLICY.merge_concat_sequence="cm"``
+
+        What you should **not** ever do is to assign :data:`iris.COMBINE_POLICY` itself,
+        e.g. ``iris.COMBINE_POLICY = CombineOptions("legacy")``, since in that case the
+        original object still exists, and is still the one in control of load/combine
+        operations.  Here, the correct approach would be
+        ``iris.COMBINE_POLICY.set("legacy")``.
+
+    >>> COMBINE_POLICY.set("legacy")
+    >>> print(COMBINE_POLICY)
+    CombineOptions(equalise_cubes_kwargs=None, merge_concat_sequence='m', merge_unique=False, repeat_until_unchanged=False, support_multiple_references=False)

+    CombineOptions(equalise_cubes_kwargs=None, merge_concat_sequence='cm', merge_unique=False, repeat_until_unchanged=False, support_multiple_references=True)
+
+    .. Note::
+
+        The name ``iris.LOAD_POLICY`` refers to the same thing as
+        ``iris.COMBINE_POLICY``, and is still usable, but is no longer recommended.

-    Applies :meth:`~iris.cube.CubeList.merge`/:meth:`~iris.cube.CubeList.concatenate`

     Parameters
     ----------
     cubes : list of :class:`~iris.cube.Cube`
         A list of cubes to combine.
     options : dict
-        Settings, as described for :class:`iris.CombineOptions`.
-    merge_require_unique : bool
-        Value for the 'unique' keyword in any merge operations.
+        Dictionary of settings options, as described for :class:`iris.CombineOptions`.

     -------
     :class:`~iris.cube.CubeList`
 
-    .. Note::
-        The ``support_multiple_references`` keyword/property has no effect on the

-
-    Notes
-    -----
-    TODO: make this public API in future.
-    At that point, change the API to support (options=None, **kwargs) + add testing of
-    those modes (notably arg type = None / str / dict).

+
+    For this example we have 'booby-trapped' the Iris loading process to force
+    errors to occur. When we load our first cube, we see the warning that
+    :const:`LOAD_PROBLEMS` has been added to:
+
+    >>> cube_a1b = iris.load_cube(iris.sample_data_path("A1B_north_america.nc"))
+    iris/...IrisLoadWarning: Not all file objects were parsed correctly. See iris.loading.LOAD_PROBLEMS for details.
+      warnings.warn(message, category=IrisLoadWarning)
+
+    Remember that Python by default suppresses duplicate warnings, so a second
+    load action does not raise another:
+
+    >>> cube_e1 = iris.load_cube(iris.sample_data_path("E1_north_america.nc"))
+
+    Examining the contents of :const:`LOAD_PROBLEMS` we can see that both files
+    experienced some problems:
+
+    >>> problems_by_file = iris.loading.LOAD_PROBLEMS.problems_by_file
+    >>> print([Path(filename).name for filename in problems_by_file.keys()])
+    ['A1B_north_america.nc', 'E1_north_america.nc']
+
+    Printing the A1B cube shows that the time dimension coordinate is missing:
+
+    >>> print(cube_a1b.summary(shorten=True))
+    air_temperature / (K)               (-- : 240; latitude: 37; longitude: 49)
+
+    A more detailed summary is available by printing :const:`LOAD_PROBLEMS`:
+
+    >>> print(iris.loading.LOAD_PROBLEMS)
+    <iris.loading.LoadProblems object at ...>:
+      .../A1B_north_america.nc: "'air_temperature' is not a valid standard_name", {'standard_name': 'air_temperature'}

+      .../E1_north_america.nc: "Example dimension coordinate error", unknown / (unknown)                 (-- : 240)
+
+
+    Below demonstrates how to explore the captured stack traces in detail:
+
+    >>> (a1b_full_name,) = [
+    ...     filename for filename in problems_by_file.keys()
+    ...     if Path(filename).name == "A1B_north_america.nc"
+    ... ]

+
+    :const:`LOAD_PROBLEMS` also captures the 'raw' information in the object

       <description>Acoustic area backscattering strength is 10 times the log10 of the ratio of the area backscattering coefficient to the reference value, 1 (m2 m-2). Area backscattering coefficient is the integral of the volume backscattering coefficient over a defined distance. Volume backscattering coefficient is the linear form of acoustic_volume_backscattering_strength_in_sea_water. For further details see MacLennan et. al (2002) doi:10.1006/jmsc.2001.1158.</description>

       <description>Acoustic equivalent area is the squared area backscattering coefficient divided by the depth integral of squared volume backscattering coefficient. Area backscattering coefficient is the integral of the volume backscattering coefficient over a defined distance. Volume backscattering coefficient is the linear form of acoustic_volume_backscattering_strength_in_sea_water. The parameter is computed to provide a value that represents the area that would be occupied if all data cells contained the mean density and is the reciprocal of acoustic_index_of_aggregation_in_sea_water. For further details see Urmy et. al (2012) doi:10.1093/icesjms/fsr205 and Woillez et. al (2007) doi.org/10.1093/icesjms/fsm025.</description>

       <description>Acoustic index of aggregation is the depth integral of squared volume backscattering coefficient divided by the squared area backscattering coefficient. Volume backscattering coefficient is the linear form of acoustic_volume_backscattering_strength_in_sea_water. Area backscattering coefficient is the integral of the volume backscattering coefficient over a defined distance. The parameter is computed to provide a value that represents the patchiness of biomass in the water column in the field of fisheries acoustics - the value is high when small areas are much denser than the rest of the distribution. The parameter is also the reciprocal of acoustic_equivalent_area_in_sea_water.

       <description>Acoustic inertia is the sum of squared distances from the acoustic_centre_of_mass weighted by the volume backscattering coefficient at each distance and normalized by the total area backscattering coefficient. Volume backscattering coefficient is the linear form of acoustic_volume_backscattering_strength_in_sea_water. Area backscattering coefficient is the integral of the volume backscattering coefficient over a defined distance.

       <description>The &quot;equivalent potential temperature&quot; is a thermodynamic quantity, with its natural logarithm proportional to the entropy of moist air, that is conserved in a reversible moist adiabatic process. Reference: AMS Glossary http://glossary.ametsoc.org/wiki/Equivalent_potential_temperature. It is the temperature of a parcel of air if all the moisture contained in it were first condensed, releasing latent heat, before moving the parcel dry adiabatically to a standard pressure, typically representative of mean sea level pressure. To specify the standard pressure to which the quantity applies, provide a scalar coordinate variable with standard name reference_pressure. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>Global average sea level change is due to change in volume of the water in the ocean, caused by mass and/or density change, or to change in the volume of the ocean basins, caused by tectonics etc. It is sometimes called &quot;eustatic&quot;, which is a term that also has other definitions. It differs from the change in the global average sea surface height relative to the centre of the Earth by the global average vertical movement of the ocean floor. Zero sea level change is an arbitrary level. Amplitude is the magnitude of a wave modelled by a sinusoidal function. A coordinate variable of harmonic_period should be used to specify the period of the sinusoidal wave. Because global average sea level change quantifies the change in volume of the world ocean, it is not calculated necessarily by considering local changes in mean sea level.</description>

       <description>Air temperature is the bulk temperature of the air, not the surface (skin) temperature. The quantity with standard name apparent_air_temperature is the perceived air temperature derived from either a combination of temperature and wind (which has standard name wind_chill_of_air_temperature) or temperature and humidity (which has standard name heat_index_of_air_temperature) for the hour indicated by the time coordinate variable. When the air temperature falls to 283.15 K or below, wind chill is used for the apparent_air_temperature. When the air temperature rises above 299.817 K, the heat index is used for apparent_air_temperature. For temperatures above 283.15 and below 299.817K, the apparent_air_temperature is the ambient air temperature (which has standard name air_temperature). References: https://digital.weather.gov/staticpages/definitions.php; WMO codes registry entry http://codes.wmo.int/grib2/codeflag/4.2/_0-0-21. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>Convective inhibition is the amount of energy per unit mass required to overcome the negatively buoyant energy exerted by the environment on a parcel of air.  Convective inhibition is often abbreviated as &quot;CIN&quot; or &quot;CINH&quot;.  It is calculated by integrating the negative temperature difference between the surrounding atmosphere and a parcel of air lifted adiabatically from a given starting height to its equilibrium level. A coordinate variable of original_air_pressure_of_lifted_parcel should be specified to indicate the starting height of the lifted parcel.</description>

       <description>In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics.  The atmosphere convective mass flux is the vertical transport of mass for a field of cumulus clouds or thermals, given by the product of air density and vertical velocity. For an area-average, cell_methods should specify whether the average is over all the area or the area of updrafts and/or downdrafts only.  &quot;Downdraft&quot; means that the flux is positive in the downward direction (negative upward).</description>

       <description>The quantity with standard name atmosphere_layer_thickness_expressed_as_geopotential_height_difference is the difference of geopotential height between two atmospheric levels. &quot;Layer&quot; means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be &quot;model_level_number&quot;, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. &quot;Thickness&quot; means the vertical extent of a layer. Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name &quot;height&quot;, which is relative to the surface.</description>

       <description>The atmosphere_stability_k_index is an index that indicates the potential of severe convection and is often referred to as simply the k index. The index is calculated as A + B - C, where A is the difference in air temperature between 850 and 500 hPa, B is the dew point temperature at 850 hPa, and C is the dew point depression (i.e. the amount by which the air temperature exceeds its dew point temperature) at 700 hPa. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The Automated Tropical Cyclone Forecasting System (ATCF) storm identifier is an 8 character string which identifies a tropical cyclone. The storm identifier has the form BBCCYYYY, where BB is the ocean basin, specifically: AL - North Atlantic basin, north of the Equator; SL - South Atlantic basin, south of the Equator; EP - North East Pacific basin, eastward of 140 degrees west longitude; CP - North Central Pacific basin, between the dateline and 140 degrees west longitude; WP - North West Pacific basin, westward of the dateline; IO - North Indian Ocean basin, north of the Equator between 40 and 100 degrees east longitude; SH - South Pacific Ocean basin and South Indian Ocean basin. CC is the cyclone number. Numbers 01 through 49 are reserved for tropical and subtropical cyclones. A cyclone number is assigned to each tropical or subtropical cyclone in each basin as it develops. Numbers are assigned in chronological order. Numbers 50 through 79 are reserved for internal use by operational forecast centers. Numbers 80 through 89 are reserved for training, exercises and testing. Numbers 90 through 99 are reserved for tropical disturbances having the potential to become tropical or subtropical cyclones. The 90&#x27;s are assigned sequentially and reused throughout the calendar year. YYYY is the four-digit year. This is calendar year for the northern hemisphere. For the southern hemisphere, the year begins July 1, with calendar year plus one. Reference: Miller, R.J., Schrader, A.J., Sampson, C.R., &amp; Tsui, T.L.

       <description>The Canadian Fire Weather Index (CFWI) is a numerical rating of potential frontal fire intensity from the Canadian Forest Fire Index System. It indicates fire intensity by combining the rate of spread with the amount of fuel being consumed and is also used for general public information about fire danger conditions. It is a function of wind speed, temperature, relative humidity, and precipitation. The calculation accounts for multiple layers of flammable material on the ground as well as fine fuels above the surface, combined with the expected rate of spread of fire. The index is open ended.</description>

       <description>&quot;Canopy&quot; means the plant or vegetation canopy. The &quot;canopy_resistance&quot; is the resistance of a compound to uptake by the vegetation canopy. It varies both with the surface and the chemical species or physical state (gas or particle). Canopy resistance is a function of the canopy stomatal resistance (Rstom), the canopy cuticle resistance (Rcuticle), and the soil resistance (Rsoil). In the case of ozone the uptake by the cuticle is small compared to the uptake through the stomata. Reference: Kerstiens and Lendzian, 1989. This means that the cuticle transfer pathway can be neglected in model parameterizations.

       <description>&quot;change_over_time_in_X&quot; means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Absolute Salinity, S_A, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). It is the mass fraction of dissolved material in sea water. Absolute Salinity incorporates the spatial variations in the composition of sea water. This type of Absolute Salinity is also called &quot;Density Salinity&quot;. TEOS-10 estimates Absolute Salinity as the salinity variable that, when used with the TEOS-10 expression for density, yields the correct density of a sea water sample even when the sample is not of Reference Composition. In practice, Absolute Salinity is often calculated from Practical Salinity using a spatial lookup table of pre-defined values of the Absolute Salinity Anomaly. It is recommended that the version of (TEOS-10) software and the associated Absolute Salinity Anomaly climatology be specified within metadata by attaching a comment attribute to the data variable. Reference: www.teos-10.org; Millero et al., 2008 doi: 10.1016/j.dsr.2007.10.001. There are also standard names for the precisely defined salinity quantities sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 onwards), sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity.</description>

       <description>The phrase &quot;change_over_time_in_X&quot; means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_water_specific_potential_enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the &quot;heat content&quot; of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

       <description>&quot;change_over_time_in_X&quot; means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. &quot;Neutral density&quot; is a variable designed so that a surface of constant neutral density everywhere has a local slope that is close to the local slope of the neutral tangent plane. At the sea surface in the equatorial Pacific neutral density is very close to the potential density anomaly. At other locations, this is not the case. For example, along a neutral density surface there is a difference of up to 0.14 kg/m^3 in the potential density anomaly at the outcrops in the Southern and Northern hemispheres.

       <description>The phrase &quot;change_over_time_in_X&quot; means change in a quantity X over a time interval, which should be defined by the bounds of the time coordinate. Practical Salinity, S_P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_water_absolute_salinity (S_A); sea_water_preformed_salinity (S_*), sea_water_reference_salinity (S_R); sea_water_cox_salinity (S_C), used for salinity observations between 1967 and 1977; and sea_water_knudsen_salinity (S_K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity.

Preformed Salinity, S*, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). Preformed Salinity is a salinity variable that is designed to be as conservative as possible, by removing the estimated biogeochemical influences on the sea water composition. Preformed Salinity is Absolute Salinity, S_A (which has the standard name sea_water_absolute_salinity), minus all contributions to sea water composition from biogeochemical processes. Preformed Salinity is the mass fraction of dissolved material in sea water.

       <description>&quot;change_over_time_in_X&quot; means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate. Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

       <description>The phrase &quot;change_over_time_in_X&quot; means change in a quantity X over a time-interval, which should be defined by the bounds of the time coordinate.Sea water temperature is the in situ temperature of the sea water. To specify the depth at which the temperature applies use a vertical coordinate variable or scalar coordinate variable. There are standard names for sea_surface_temperature, sea_surface_skin_temperature, sea_surface_subskin_temperature and sea_surface_foundation_temperature which can be used to describe data located at the specified surfaces. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard &quot;scales&quot;. These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>Cloud liquid water mixing ratio of a parcel of air is the ratio of the mass of liquid water to the mass of dry air. &quot;Cloud liquid water&quot; refers to the liquid phase of cloud water. A diameter of 0.2 mm has been suggested as an upper limit to the size of drops that shall be regarded as cloud drops; larger drops fall rapidly enough so that only very strong updrafts can sustain them. Any such division is somewhat arbitrary, and active cumulus clouds sometimes contain cloud drops much larger than this.

       <description>The quantity with standard name concentration_of_colored_dissolved_organic_matter_in_sea_water_expressed_as_equivalent_mass_fraction_of_quinine_sulfate_dihydrate is also commonly known as Chromophoric Dissolved Organic Matter (CDOM). CDOM plays an important role in the carbon cycling and biogeochemistry of coastal waters. It occurs naturally in aquatic environments primarily as a result of tannins released from decaying plant and animal matter, which can enter coastal areas in river run-off containing organic materials leached from soils. When present in high concentrations, it imparts a brown or yellowish color to water. Its presence can negatively impact fish populations by reducing dissolved oxygen concentrations to harmful levels and by releasing nutrients and metals that contaminate the water. Increased understanding of the role of CDOM will further our ability to manage and protect coastal ecosystems. Sensors are commonly calibrated against a 100 parts per billion (ppb) quinine sulfate dihydrate solution, a fluorescent reference standard commonly used with CDOM sensors. CDOM sensors therefore report in &quot;QSDE&quot; (quinine sulfate dihydrate equivalents). It is important to note, however, that CDOM concentrations in QSDE are not necessarily equivalent to the in situ CDOM concentrations in ppb.</description>

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. The cloud area fraction is for the whole atmosphere column, as seen from the surface or the top of the atmosphere. For the cloud area fraction between specified levels in the atmosphere, standard names including &quot;cloud_area_fraction_in_atmosphere_layer&quot; are used. Standard names also exist for high, medium and low cloud types. Convective cloud is that produced by the convection schemes in an atmosphere model. Cloud area fraction is also called &quot;cloud amount&quot; and &quot;cloud cover&quot;.</description>

       <description>Covariance refers to the sample covariance rather than the population covariance. The quantity with standard name covariance_over_longitude_of_northward_wind_and_air_temperature is the covariance of the deviations of meridional air velocity and air temperature about their respective zonal mean values. The data variable must be accompanied by a vertical coordinate variable or scalar coordinate variable and is calculated on an isosurface of that vertical coordinate. &quot;Northward&quot; indicates a vector component which is positive when directed northward (negative southward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name &quot;upward_air_velocity&quot;). Air temperature is the bulk temperature of the air, not the surface (skin) temperature. It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>This variable quantifies the temperature difference between the top (sea_surface_subskin_temperature) and bottom (sea_surface_foundation_temperature) of the diurnal warm layer. This diurnal warm layer, caused by absorption of solar radiation in the absence of strong mixing, together with a cool skin effect, account for the total temperature difference between the sea_surface_skin_temperature and the sea_surface_foundation_temperature. The cool skin effect is associated with the turbulent and infrared radiative heat loss at the air-sea interface. Freshwater fluxes may also affect this variable (sea_surface_subskin_temperature_minus_sea_surface_foundation_temperature).</description>

       <description>This variable quantifies the temperature difference between the top of the diurnal warm layer (sea_surface_subskin_temperature) and the in-situ measured sea surface temperature at depth (sea_surface_temperature). A diurnal warm layer can develop in the top few meters of the ocean through the absorption of solar radiation, if surface mixing is sufficiently weak.</description>

       <description>Sea surface temperature is usually abbreviated as &quot;SST&quot;. It is the temperature of sea water near the surface (including the part under sea-ice, if any), not the skin or interface temperature, whose standard names are sea_surface_skin_temperature and surface_temperature, respectively. For the temperature of sea water at a particular depth or layer, a data variable of &quot;sea_water_temperature&quot; with a vertical coordinate axis should be used. Air temperature is the bulk temperature of the air, not the surface (skin) temperature. It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>In some atmosphere models, the difference of air pressure from model reference is a prognostic variable, instead of the air pressure itself. The model reference air pressure is a model-dependent constant. Air pressure is the force per unit area which would be exerted when the moving gas molecules of which the air is composed strike a theoretical surface of any orientation.</description>

       <description>The phrase &quot;direction_of_X&quot; means direction of a vector, a bearing. &quot;Displacement&quot; means the change in geospatial position of an object that has moved over time. If possible, the time interval over which the motion took place should be specified using a bounds variable for the time coordinate variable. A displacement can be represented as a vector. Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. In that case, &quot;displacement&quot; is also the distance across the earth&#x27;s surface calculated from the change in a moving object&#x27;s geospatial position between the start and end of the time interval associated with the displacement variable. The &quot;direction of displacement&quot; is the angle between due north and the displacement vector. &quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.</description>

       <description>Downwelling radiation is radiation from above. It does not mean &quot;net downward&quot;. The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. The term &quot;shortwave&quot; means shortwave radiation. When thought of as being incident on a surface, a radiative flux is sometimes called &quot;irradiance&quot;. In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called &quot;vector irradiance&quot;. In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. A phrase &quot;assuming_condition&quot; indicates that the named quantity is the value which would obtain if all aspects of the system were unaltered except for the assumption of the circumstances specified by the condition. This 3D ozone field acts as a reference ozone field in a diagnostic call to the model&#x27;s radiation scheme. It is expressed in terms of mole fraction of ozone in air. It may be observation-based or model-derived. It may be from any time period. By using the same ozone reference in the diagnostic radiation call in two model simulations and calculating differences between the radiative flux diagnostics from the prognostic call to the radiation scheme and the diagnostic call to the radiation scheme with the ozone reference, an instantaneous radiative forcing for ozone can be calculated.</description>

Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component.

       <description>Isotopic enrichment of 14C, often called d14C or delta14C (lower case delta), is used to calculate the fossil fuel contribution to atmospheric carbon dioxide using isotopic ratios of carbon. It is a parameterisation of the 14C/12C isotopic ratio in the sample with respect to the isotopic ratio in a reference standard. It is computed using the formula (((14C/12C)sample / (14C/12C)standard) - 1) * 1000. The quantity called D14C, or Delta14C (upper case delta) is d14C corrected for isotopic fractionation using the 13C/12C ratio as follows: D14C = d14C - 2(dC13 + 25)(1+d14C/1000). If the sample is enriched in 14C relative to the standard, then the data value is positive. Reference: Stuiver, M. and H.A. Polach, 1977, Discussion reporting of 14C data, Radiocarbon, Volume 19, No. 3, 355-363, doi: 10.1017/S0033822200003672. The reference standard used in the calculation of delta14C should be specified by attaching a long_name attribute to the data variable. &quot;C&quot; means the element carbon and &quot;14C&quot; is the radioactive isotope &quot;carbon-14&quot;, having six protons and eight neutrons and used in radiocarbon dating.</description>

       <description>The Ertel potential vorticity is the scalar product of the atmospheric absolute vorticity vector and the gradient of potential temperature. It is a conserved quantity in the absence of friction and heat sources [AMS Glossary, http://glossary.ametsoc.org/wiki/Ertel_potential_vorticity]. A frequently used simplification of the general Ertel potential vorticity considers the Earth rotation vector to have only a vertical component. Then, only the vertical contribution of the scalar product is calculated. It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>Downwelling radiation is radiation from above. It does not mean &quot;net downward&quot;. The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. The surface called &quot;surface&quot; means the lower boundary of the atmosphere. The quantity with standard name fraction_of_surface_downwelling_photosynthetic_radiative_flux_absorbed_by_vegetation, often called Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), is the fraction of incoming solar radiation in the photosynthetically active radiation spectral region that is absorbed by a vegetation canopy. &quot;Photosynthetic&quot; radiation is the part of the spectrum which is used in photosynthesis e.g. 400-700 nm. The range of wavelengths could be specified precisely by the bounds of a coordinate of &quot;radiation_wavelength&quot;. When thought of as being incident on a surface, a radiative flux is sometimes called &quot;irradiance&quot;. In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called &quot;vector irradiance&quot;. In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. &quot;Vegetation&quot; means any plants e.g. trees, shrubs, grass. The term &quot;plants&quot; refers to the kingdom of plants in the modern classification which excludes fungi. Plants are autotrophs i.e. &quot;producers&quot; of biomass using carbon obtained from carbon dioxide.</description>

       <description>The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. A reference ellipsoid is a regular mathematical figure that approximates the irregular shape of the geoid. A number of reference ellipsoids are defined for use in the field of geodesy. To specify which reference ellipsoid is being used, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention.</description>

Sea-ice algae (or simply &#x27;ice algae&#x27; when the context of sea ice is clear) refer to algae uniquely able to thrive within the sea-ice environment. This distinction from phytoplankton is essential, as several phytoplankton species that become trapped in sea ice eventually perish due to a lack of genetic adaptation or acclimation strategies to survive such conditions. By referring to &#x27;sea-ice algae,&#x27; we highlight these algae&#x27;s specific features and ecological significance within the sea-ice habitat.</description>

Heat index is only defined when the ambient air temperature is at or above 299.817 K. References: https://www.weather.gov/safety/heat-index; WMO codes registry entry http://codes.wmo.int/grib2/codeflag/4.2/_0-0-12. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. High type clouds are: Cirrus, Cirrostratus, Cirrocumulus. X_type_cloud_area_fraction is generally determined on the basis of cloud type, though Numerical Weather Prediction (NWP) models often calculate them based on the vertical location of the cloud. For the cloud area fraction between specified levels in the atmosphere, standard names including &quot;cloud_area_fraction_in_atmosphere_layer&quot; are used. Standard names referring only to &quot;cloud_area_fraction&quot; should be used for quantities for the whole atmosphere column.

Excess ice is the volume of ice in the ground which exceeds the total pore volume that the ground would have under natural unfrozen conditions. Due to the presence of ground ice, the total water content of a frozen soil may exceed that corresponding to its normally consolidated state when unfrozen. As a result, upon thawing, a soil containing excess ice will settle under its own weight until it attains its consolidated state. Reference: van Everdingen, R.

       <description>The phrase &quot;integral_wrt_X_of_Y&quot; means int Y dX. To specify the limits of the integral the data variable should have an axis for X and associated coordinate bounds. If no axis for X is associated with the data variable, or no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is air the integral is assumed to be calculated over the full depth of the atmosphere.

Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_water_specific_potential_enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the &quot;heat content&quot; of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

If no axis for X is associated with the data variable, or no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is air the integral is assumed to be calculated over the full depth of the atmosphere. The phrase &quot;wrt&quot; means &quot;with respect to&quot;. The phrase &quot;product_of_X_and_Y&quot; means X*Y. Depth is the vertical distance below the surface. Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. Practical salinity units are dimensionless. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity. Sea water density is the in-situ density (not the potential density). For Boussinesq models, density is the constant Boussinesq reference density, a quantity which has the standard name reference_sea_water_density_for_boussinesq_approximation.</description>

Depth is the vertical distance below the surface. Practical Salinity, S_P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard  potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_water_absolute_salinity (S_A); sea_water_preformed_salinity (S_*), sea_water_reference_salinity (S_R); sea_water_cox_salinity (S_C), used for salinity observations between 1967 and 1977; and sea_water_knudsen_salinity (S_K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity.

Depth is the vertical distance below the surface. Sea water temperature is the in situ temperature of the sea water. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard &quot;scales&quot;. These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90. References: Barber, 1969, doi: 10.1088/0026-1394/5/2/001; UNESCO, 1981; Saunders, 1990, WOCE Newsletter, 10, September 1990. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. The cloud area fraction is for the whole atmosphere column, as seen from the surface or the top of the atmosphere. For the cloud area fraction between specified levels in the atmosphere, standard names including &quot;cloud_area_fraction_in_atmosphere_layer&quot; are used. Standard names also exist for high, medium and low cloud types. The ISCCP cloud area fraction is diagnosed from atmosphere model output by the ISCCP simulator software in such a way as to be comparable with the observational diagnostics of ISCCP (the International Satellite Cloud Climatology Project). Cloud area fraction is also called &quot;cloud amount&quot; and &quot;cloud cover&quot;.</description>

       <description>The phrase &quot;magnitude_of_X&quot; means magnitude of a vector X. &quot;Displacement&quot; means the change in geospatial position of an object that has moved over time. If possible, the time interval over which the motion took place should be specified using a bounds variable for the time coordinate variable. A displacement can be represented as a vector. Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. &quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.</description>

A chemical or biological species denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. The phrase &quot;expressed_as&quot; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. Chlorophylls are the green pigments found in most plants, algae and cyanobacteria; their presence is essential for photosynthesis to take place. There are several different forms of chlorophyll that occur naturally. All contain a chlorin ring (chemical formula C20H16N4) which gives the green pigment and a side chain whose structure varies. The naturally occurring forms of chlorophyll contain between 35 and 55 carbon atoms. &quot;Calcareous phytoplankton&quot; are phytoplankton that produce calcite. Calcite is a mineral that is a polymorph of calcium carbonate. The chemical formula of calcite is CaCO3. Phytoplankton are algae that grow where there is sufficient light to support photosynthesis.</description>

       <description>&quot;Mass concentration&quot; means mass per unit volume and is used in the construction &quot;mass_concentration_of_X_in_Y&quot;, where X is a material constituent of Y. A chemical species or biological group denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. &quot;Dry aerosol particles&quot; means aerosol particles without any water uptake. Chemically, &quot;carbon&quot; is the total sum of elemental, organic, and inorganic carbon. In measurements of carbonaceous aerosols, inorganic carbon is neglected and its mass is assumed to be distributed between the elemental and organic carbon components of the aerosol particles.

A chemical species denoted by X may be described by a single term such as &#x27;nitrogen&#x27; or a phrase such as &#x27;nox_expressed_as_nitrogen&#x27;. Chlorophylls are the green pigments found in most plants, algae and cyanobacteria; their presence is essential for photosynthesis to take place. There are several different forms of chlorophyll that occur naturally. All contain a chlorin ring (chemical formula C20H16N4) which gives the green pigment and a side chain whose structure varies. The naturally occurring forms of chlorophyll contain between 35 and 55 carbon atoms.</description>

A chemical species or biological group denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. &quot;Cloud liquid water&quot; refers to the liquid phase of cloud water. A diameter of 0.2 mm has been suggested as an upper limit to the size of drops that shall be regarded as cloud drops; larger drops fall rapidly enough so that only very strong updrafts can sustain them. Any such division is somewhat arbitrary, and active cumulus clouds sometimes contain cloud drops much larger than this.

A chemical or biological species denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. &quot;Clox&quot; describes a family of chemical species consisting of inorganic chlorine compounds with the exception of hydrogen chloride (HCl) and chlorine nitrate (ClONO2). The phrase &quot;expressed_as&quot; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. &quot;Clox&quot; is the term used in standard names for all species belonging to the family that are represented within a given model. The list of individual species that are included in a quantity with a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. &quot;Inorganic chlorine&quot;, sometimes referred to as Cly, describes a family of chemical species which result from the degradation of source gases containing chlorine (CFCs, HCFCs, VSLS) and natural inorganic chlorine sources such as sea salt and other aerosols. Standard names that use the term &quot;inorganic_chlorine&quot; are used for quantities that contain all inorganic chlorine species including HCl and ClONO2.</description>

       <description>&quot;Mass concentration&quot; means mass per unit volume and is used in the construction &quot;mass_concentration_of_X_in_Y&quot;, where X is a material constituent of Y. A chemical species or biological group denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. &quot;Dry aerosol particles&quot; means aerosol particles without any water uptake. Chemically, &quot;organic carbon aerosol&quot; refers to the carbonaceous fraction of particulate matter contained in any of the vast number of compounds where carbon is chemically combined with hydrogen and other elements like O, S, N, P, Cl, etc. In measurements of carbonaceous aerosols, organic carbon samples may also include some inorganic carbon compounds, whose mass is neglected and assumed to be distributed between the elemental and organic carbon components of the aerosol particles.

       <description>In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. Examples of &quot;forestry and agricultural products&quot; are paper, cardboard, furniture, timber for construction, biofuels and food for both humans and livestock. Models that simulate land use changes have one or more pools of carbon that represent these products in order to conserve carbon and allow its eventual release into the atmosphere, for example, when the products decompose in landfill sites. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. The definition of &quot;crop&quot; is model dependent, for example, some models may include fruit trees, trees grown for timber or other types of agricultural and forestry planting as crops. Crop harvesting means the human activity of collecting plant materials for the purpose of turning them into forestry or agricultural products.</description>

A chemical species denoted by X may be described by a single term such as &quot;nitrogen&quot; or a phrase such as &quot;nox_expressed_as_nitrogen&quot;. The phrase &quot;expressed_as&quot; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. &quot;Dry aerosol particles&quot; means aerosol particles without any water uptake. &quot;Pm2p5 aerosol&quot; means atmospheric particulate compounds with an aerodynamic diameter of less than or equal to 2.5 micrometers. The phrase &quot;sea_salt_cation&quot; is the term used in standard names to describe collectively the group of cationic species that occur in sea salt. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Sea salt cations are mainly sodium (Na+), but also include potassium (K+), magnesium (Mg2+), calcium (Ca2+) and rarer cations. Where possible, the data variable should be accompanied by a complete description of the ions represented, for example, by using a comment attribute.</description>

       <description>&quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs. Axial strain is the symmetric component of the tensor representing the gradient of internal forces (e.g. in ice). Strain rate refers to off-diagonal element(s) of the strain tensor (a single element for horizontal shear strain). &quot;Horizontal&quot; refers to the local horizontal in the location of the sea ice, i.e., perpendicular to the local gravity vector. Each of the strain components is defined with respect to a frame of reference. &quot;Coordinate rotation&quot; refers to the range of all possible orientations of the frame of reference. The shear strain has a maximum value relative to one of these orientations. The second invariant of strain rate, often referred to as the maximum shear strain [rate], is the maximum over coordinate rotations of the shear strain rate.</description>

       <description>&quot;Content&quot; indicates a quantity per unit area. The &quot;soil content&quot; of a quantity refers to the vertical integral from the surface down to the bottom of the soil model. For the content between specified levels in the soil, standard names including content_of_soil_layer are used. Soil carbon is returned to the atmosphere as the organic matter decays. The decay process takes varying amounts of time depending on the composition of the organic matter, the temperature and the availability of moisture. A carbon &quot;soil pool&quot; means the carbon contained in organic matter which has a characteristic period over which it decays and releases carbon into the atmosphere. &quot;Medium soil pool&quot; refers to the decay of organic matter in soil with a characteristic period of between ten and one hundred years under reference climate conditions of a temperature of 20 degrees Celsius and no water limitations.</description>

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. Middle type clouds are: Altostratus, Altocumulus, Nimbostratus. X_type_cloud_area_fraction is generally determined on the basis of cloud type, though Numerical Weather Prediction (NWP) models often calculate them based on the vertical location of the cloud. For the cloud area fraction between specified levels in the atmosphere, standard names including &quot;cloud_area_fraction_in_atmosphere_layer&quot; are used. Standard names referring only to &quot;cloud_area_fraction&quot; should be used for quantities for the whole atmosphere column. Cloud area fraction is also called &quot;cloud amount&quot; and &quot;cloud cover&quot;.</description>

       <description>The phrase &quot;tendency_of_X&quot; means derivative of X with respect to time. The phrase &quot;minus_tendency&quot; means that the quantity described takes the opposite sign convention to that for the quantity which has the same standard name apart from this phrase, i.e. the two quantities differ from one another by a factor of -1. Thus a &quot;minus_tendency&quot; in the atmosphere means a positive deposition rate onto the underlying surface. &quot;Content&quot; indicates a quantity per unit area. The &quot;atmosphere content&quot; of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including &quot;content_of_atmosphere_layer&quot; are used. The phrase &quot;expressed_as&quot; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. &quot;Nitrogen compounds&quot; summarizes all chemical species containing nitrogen atoms. Usually, particle bound and gaseous nitrogen compounds, such as atomic nitrogen (N), nitrogen monoxide (NO), nitrogen dioxide (NO2), dinitrogen pentoxide (N2O5), nitric acid (HNO3), nitrate (NO3-), peroxynitric acid (HNO4), ammonia (NH3), ammonium (NH4+), bromine nitrate (BrONO2), chlorine nitrate (ClONO2) and organic nitrates (most notably peroxyacetyl nitrate, sometimes referred to as PAN, (CH3COO2NO2)) are included. The list of individual species that are included in this quantity can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. &quot;Deposition&quot; is the sum of wet and dry deposition.</description>

Sigma-theta of sea water is the potential density (i.e. the density when moved adiabatically to a reference pressure) of water having the same temperature and salinity, minus 1000 kg m-3. The quantity model_level_number_at_base_of_ocean_mixed_layer_defined_by_sigma_theta is sometimes referred to as the &quot;bowl index&quot;.</description>

       <description>The quantity with standard name model_level_number_at_sea_floor is the depth of the ocean expressed in model levels. This could be a non-integer value because some ocean models use partial cells close to the sea floor.  For example, if this field were 23.4 at some location, it would mean the water column at that point comprised 23 full model levels plus 40% occupancy of the lowest (24th) gridcell.</description>

       <description>The MODIS cloud area fraction is diagnosed from atmosphere model output by the MODIS simulator software in such a way as to be comparable with the observational diagnostics of MODIS (Moderate Resolution Imaging Spectroradiometer). Cloud area fraction is also called “cloud amount” and “cloud cover.” As seen from above, mean fraction of grid column occupied by cloud of optical depths and heights specified by the tau and pressure intervals given above. Dimensions of the histogram are cloud top pressure and cloud optical depth. To distinguish that these are cloud area fractions as seen by a specific satellite instrument simulator, not the same as cloud area fractions diagnosed by the native model, the prefix format of satellite name_ is employed. &quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion.</description>

There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_level_number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. Quantities defined for a soil layer must have a vertical coordinate variable with boundaries indicating the extent of the layer(s). The field capacity of soil is the maximum content of water it can retain against gravitational drainage.</description>

Net primary production is the excess of gross primary production (rate of synthesis of biomass from inorganic precursors) by autotrophs (&quot;producers&quot;), for example, photosynthesis in plants or phytoplankton, over the rate at which the autotrophs themselves respire some of this biomass. &quot;Productivity&quot; means production per unit area. The phrase &quot;expressed_as&quot; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. &quot;Miscellaneous phytoplankton&quot; are all those phytoplankton that are not diatoms, diazotrophs, calcareous phytoplankton, picophytoplankton or other separately named components of the phytoplankton population. Phytoplankton are algae that grow where there is sufficient light to support photosynthesis.</description>

       <description>The Burning Index (BI) is a numeric value closely related to the flame length in feet multiplied by 10, which is related to the contribution of fire behaviour to the effort of containing a fire. The BI is a function of fire spread and fire intensity and is derived from a combination of Spread and Energy Release Components. The Spread Component is a rating of the forward rate of spread of a head fire and wind is a key input. The scale is open ended which allows the range of numbers to adequately define fire problems, even in time of low to moderate fire danger. Computed BI values represent the near upper limit to be expected on the rating area. In other words, if a fire occurs in the worst fuel, weather and topography conditions of the rating area, these numbers indicate its expected fire line intensities and flame length. It is an index in the US National Fire Danger Rating System. The US National Fire Danger Rating System comprises several numeric indexes that rate the potential over a large area for wildland fires to ignite, spread, and require action to suppress or manage.

       <description>The Energy Release Component (ERC) is a number related to the available energy per unit area within the flaming front at the head of a fire. It is usually given in BTU ft-2. Daily variations in ERC are due to changes in moisture content of the various fuels present, both live and dead. It may also be considered a composite fuel moisture value as it reflects the contribution that all live and dead fuels have to potential fire intensity. Energy Release Component is a cumulative index. The scale is open-ended and relative. Energy Release Component values depend on the fuel model input into the calculations and interpretation of precise values varies with ecology and region. It is an index in the US National Fire Danger Rating System.

       <description>Severe Fire Danger Index (SFDI) is the normalized product of normalized Energy Release Component (ERC) and normalized Burning Index (BI) from the United States National Fire Danger Rating System (NFDRS). While SFDI is not officially part of the National Fire Danger Rating System, it is related to and intended to supplement NFDRS. It is commonly categorized into five classes based on percentile: low (0-60), moderate (60-80), high (80-90), very high (90-97), and extreme (97-100). It can be extended to future conditions by introducing an unprecedented category for values above the historical 100th percentile. As it is locally normalized, its interpretation remains the same across space.</description>

The phrase &quot;non_tidal_elevation&quot; describes the contribution to sea surface height variability made by processes other than astronomic forcing of the ocean and shallow water resonance of tidal components. These processes include storm surge (due to a combination of meteorological forcing of the ocean and interaction between the generated surge and tides), effects of surface ocean waves, and seasonal and climatic variation in ocean density and circulation. The contribution made by each process varies according to the averaging time of the variable as described by the bounds and cell_methods attributes of the data variable.</description>

       <description>&quot;Normalized_difference_vegetation_index&quot;, usually abbreviated to NDVI, is an index calculated from reflectances measured in the visible and near infrared channels.  It is calculated as NDVI = (NIR - R) / (NIR + R) where NIR is the reflectance in the near-infrared band and R is the reflectance in the red visible band.  Reflectance is the ratio of the reflected over the incoming radiation in each spectral band.  The calculated value of NDVI depends on the precise definitions of the spectral bands and these definitions may vary between different models and remote sensing instruments.</description>

       <description>&quot;Northward&quot; indicates a vector component which is positive when directed northward (negative southward). &quot;Displacement&quot; means the change in geospatial position of an object that has moved over time. If possible, the time interval over which the motion took place should be specified using a bounds variable for the time coordinate variable. A displacement can be represented as a vector. Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. A northward displacement is the distance calculated from the change in a moving object&#x27;s latitude between the start and end of the time interval associated with the displacement variable. &quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.</description>

       <description>&quot;Number concentration&quot; means the number of particles or other specified objects per unit volume. The phrase &quot;stratiform_liquid_water_cloud_top&quot; refers to the top of the highest stratiform liquid water cloud. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). &quot;Cloud liquid water&quot; refers to the liquid phase of cloud water. A diameter of 0.2 mm has been suggested as an upper limit to the size of drops that shall be regarded as cloud drops; larger drops fall rapidly enough so that only very strong updrafts can sustain them. Any such division is somewhat arbitrary, and active cumulus clouds sometimes contain cloud drops much larger than this.

       <description>&quot;Ocean rigid lid pressure&quot; means the pressure at the surface of an ocean model assuming that it is bounded above by a rigid lid. &quot;Sea surface height&quot; is a time-varying quantity. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. To specify which geoid or geopotential datum is being used as a reference level, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention.</description>

       <description>The optical thickness is the integral along the path of radiation of a volume scattering/absorption/attenuation coefficient. The radiative flux is reduced by a factor exp(-optical_thickness) on traversing the path. A coordinate variable of radiation_wavelength or radiation_frequency can be specified to indicate that the optical thickness applies at specific wavelengths or frequencies. &quot;Layer&quot; means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be model_level_number, but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. &quot;Ambient_aerosol&quot; means that the aerosol is measured or modelled at the ambient state of pressure, temperature and relative humidity that exists in its immediate environment. &quot;Ambient aerosol particles&quot; are aerosol particles that have taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the particles.

       <description>Global average sea level change is due to change in volume of the water in the ocean, caused by mass and/or density change, or to change in the volume of the ocean basins, caused by tectonics etc. It is sometimes called &quot;eustatic&quot;, which is a term that also has other definitions. It differs from the change in the global average sea surface height relative to the centre of the Earth by the global average vertical movement of the ocean floor. Zero sea level change is an arbitrary level. Phase is the initial angle of a wave modelled by a sinusoidal function. A coordinate variable of harmonic_period should be used to specify the period of the sinusoidal wave. Because global average sea level change quantifies the change in volume of the world ocean, it is not calculated necessarily by considering local changes in mean sea level.</description>

       <description>Sway is a displacement along an axis that is perpendicular to both the local vertical axis and the nominal forward motion direction of the platform. Sway is relative to the &quot;at rest&quot; position of the platform with respect to the axis of displacement. The &quot;at rest&quot; position of the platform may change over time. &quot;Port&quot; indicates that positive values of sway represent the platform moving left as viewed by an observer on top of the platform facing forward. The standard name platform_sway_starboard should be used for data having the opposite sign convention. The standard name platform_sway should be chosen only if the sign convention of the data is unknown. A &quot;platform&quot; is a structure or vehicle that serves as a base for mounting sensors.

       <description>The construction &quot;probability_distribution_of_X_over_Z&quot; means that the data variable is a number in the range 0.0-1.0 for each range of X, where X varies over Z. The data variable should have an axis for X. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name &quot;upward_air_velocity&quot;). The phrase &quot;from_direction&quot; is used in the construction X_from_direction and indicates the direction from which the velocity vector of X is coming. The direction is a bearing in the usual geographical sense, measured positive clockwise from due north. In meteorological reports, the direction of the wind vector is usually (but not always) given as the direction from which it is blowing (&quot;wind_from_direction&quot;) (westerly, northerly, etc.). In other contexts, such as atmospheric modelling, it is often natural to give the direction in the usual manner of vectors as the heading or the direction to which it is blowing (&quot;wind_to_direction&quot;) (eastward, southward, etc.).</description>

       <description>&quot;product_of_X_and_Y&quot; means X*Y. A velocity is a vector quantity. &quot;Eastward&quot; indicates a vector component which is positive when directed eastward (negative westward). Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) The phrase &quot;tendency_of_X&quot; means derivative of X with respect to time. The Lagrangian tendency of a quantity is its rate of change following the motion of the fluid, also called the &quot;material derivative&quot; or &quot;convective derivative&quot;. The Lagrangian tendency of air pressure, often called &quot;omega&quot;, plays the role of the upward component of air velocity when air pressure is being used as the vertical coordinate. If the vertical air velocity is upwards, it is negative when expressed as a tendency of air pressure; downwards is positive. Air pressure is the force per unit area which would be exerted when the moving gas molecules of which the air is composed strike a theoretical surface of any orientation.</description>

       <description>&quot;product_of_X_and_Y&quot; means X*Y. A velocity is a vector quantity. &quot;Northward&quot; indicates a vector component which is positive when directed northward (negative southward). Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

The &quot;instrument&quot; (examples are radar and lidar) is the device used to make the observation. The &quot;scatterers&quot; are what causes the transmitted signal to be returned to the instrument (examples are aerosols, hydrometeors and refractive index irregularities in the air). A standard name referring to time taken for a radio signal to propagate from the emitting instrument to a scattering volume and back to an instrument.</description>

       <description>The average radius of a central region of clouds in tropical cyclones lacking well-defined eye features, which is computed by averaging the great circle distance in four cardinal directions. The radius in each direction is measured from the estimated storm center position to a warm point that exceeds a threshold brightness temperature at top of atmosphere limit.

       <description>The &quot;reaction rate&quot; is the rate at which the reactants of a chemical reaction form the products. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. The rate of &quot;hydroxyl radical destruction due to reaction with nmvoc&quot; is the nmvoc reactivity with regard to reactions with OH. It is the weighted sum of the reactivity of all individual nmvoc species with OH. The chemical formula for the hydroxyl radical is OH. In chemistry, a &quot;radical&quot; is a highly reactive, and therefore short lived, species. The abbreviation &quot;nmvoc&quot; means non methane volatile organic compounds; &quot;nmvoc&quot; is the term used in standard names to describe the group of chemical species having this classification that are represented within a given model. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute.</description>

       <description>The quantity with standard name ratio_of_sea_water_potential_temperature_anomaly_to_relaxation_timescale is a correction term applied to modelled sea water potential temperature. The term is estimated as the deviation of model local sea water potential temperature from an observation-based climatology (e.g. World Ocean Database) weighted by a user-specified relaxation coefficient in s-1 (1/(relaxation timescale)). Potential temperature is the temperature a parcel of air or sea water would have if moved adiabatically to sea level pressure. The phrase &quot;ratio_of_X_to_Y&quot; means X/Y. The term &quot;anomaly&quot; means difference from climatology. It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The quantity with standard name ratio_of_sea_water_practical_salinity_anomaly_to_relaxation_timescale is a correction term applied to modelled sea water practical salinity. The term is estimated as the deviation of model local sea water practical salinity from an observation-based climatology (e.g. World Ocean Database) weighted by a user-specified relaxation coefficient in s-1 (1/(relaxation timescale)). The phrase &quot;ratio_of_X_to_Y&quot; means X/Y. The term &quot;anomaly&quot; means difference from climatology. Practical Salinity, S_P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_water_absolute_salinity (S_A); sea_water_preformed_salinity (S_*), sea_water_reference_salinity (S_R); sea_water_cox_salinity (S_C), used for salinity observations between 1967 and 1977; and sea_water_knudsen_salinity (S_K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity.

       <description>The ratio of volume extinction coefficient to volume backwards scattering coefficient by ranging instrument in air due to ambient aerosol particles (often called &quot;lidar ratio&quot;) is the ratio of the &quot;volume extinction coefficient&quot; and the &quot;volume backwards scattering coefficient of radiative flux by ranging instrument in air due to ambient aerosol particles&quot;. The ratio is assumed to be related to the same wavelength of incident radiation. &quot;Ambient_aerosol&quot; means that the aerosol is measured or modelled at the ambient state of pressure, temperature and relative humidity that exists in its immediate environment. &quot;Ambient aerosol particles&quot; are aerosol particles that have taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the particles. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.</description>

       <description>The quantity with standard name sea_ice_temperature_expressed_as_heat_content is calculated relative to the heat content of ice at zero degrees Celsius, which is assumed to have a heat content of zero Joules. The phrase &quot;expressed_as_heat_content&quot; means that this quantity is calculated as the specific heat capacity times density of sea ice multiplied by the temperature of the sea ice in the grid cell and integrated over depth. If used for a layer heat content, coordinate bounds should be used to define the extent of the layers. If no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is sea ice the integral is assumed to be calculated over the full depth of the ice. &quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.</description>

       <description>&quot;x&quot; indicates a vector component along the grid x-axis, positive with increasing x. &quot;Displacement&quot; means the change in geospatial position of an object that has moved over time. If possible, the time interval over which the motion took place should be specified using a bounds variable for the time coordinate variable. A displacement can be represented as a vector. Such a vector should however not be interpreted as describing a rectilinear, constant speed motion but merely as an indication that the start point of the vector is found at the tip of the vector after the time interval associated with the displacement variable. A displacement does not prescribe a trajectory. Sea ice displacement can be defined as a two-dimensional vector, with no vertical component. An x displacement is calculated from the difference in the moving object&#x27;s grid x coordinate between the start and end of the time interval associated with the displacement variable. &quot;Sea ice&quot; means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.</description>

       <description>The sea surface foundation temperature is the water temperature that is not influenced by a thermally stratified layer of diurnal temperature variability (either by daytime warming or nocturnal cooling). The foundation temperature is named to indicate that it is the temperature from which the growth of the diurnal thermocline develops each day, noting that on some occasions with a deep mixed layer there is no clear foundation temperature in the surface layer. In general, sea surface foundation temperature will be similar to a night time minimum or pre-dawn value at depths of between approximately 1 and 5 meters. In the absence of any diurnal signal, the foundation temperature is considered equivalent to the quantity with standard name sea_surface_subskin_temperature. The sea surface foundation temperature defines a level in the upper water column that varies in depth, space, and time depending on the local balance between thermal stratification and turbulent energy and is expected to change slowly over the course of a day. If possible, a data variable with the standard name sea_surface_foundation_temperature should be used with a scalar vertical coordinate variable to specify the depth of the foundation level. Sea surface foundation temperature is measured at the base of the diurnal thermocline or as close to the water surface as possible in the absence of thermal stratification. Only in situ contact thermometry is able to measure the sea surface foundation temperature. Analysis procedures must be used to estimate sea surface foundation temperature value from radiometric satellite measurements of the quantities with standard names sea_surface_skin_temperature and sea_surface_subskin_temperature. Sea surface foundation temperature provides a connection with the historical concept of a &quot;bulk&quot; sea surface temperature considered representative of the oceanic mixed layer temperature that is typically represented by any sea temperature measurement within the upper ocean over a depth range of 1 to approximately 20 meters. The general term, &quot;bulk&quot; sea surface temperature, has the standard name sea_surface_temperature with no associated vertical coordinate axis. Sea surface foundation temperature provides a more precise, well defined quantity than &quot;bulk&quot; sea surface temperature and, consequently, is more representative of the mixed layer temperature. The temperature of sea water at a particular depth (other than the foundation level) should be reported using the standard name sea_water_temperature and, wherever possible, supplying a vertical coordinate axis or scalar coordinate variable. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>&quot;Height_above_X&quot; means the vertical distance above the named surface X. &quot;Sea surface height&quot; is a time-varying quantity. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. To specify which geoid or geopotential datum is being used as a reference level, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention. By definition of the geoid, the global average of the time-mean sea surface height (i.e. mean sea level) above the geoid must be zero. The standard name for the height of the sea surface above mean sea level is sea_surface_height_above_mean_sea_level.

       <description>Sea surface salinity is the salt content of sea water close to the sea surface, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. Sea surface salinity is often abbreviated as &quot;SSS&quot;. For the salinity of sea water at a particular depth or layer, a data variable of &quot;sea_water_salinity&quot; or one of the more precisely defined salinities should be used with a vertical coordinate axis. There are standard names for the precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

       <description>The sea surface skin temperature is the temperature measured by an infrared radiometer typically operating at wavelengths in the range 3.7 - 12 micrometers. It represents the temperature within the conductive diffusion-dominated sub-layer at a depth of approximately 10 - 20 micrometers below the air-sea interface. Measurements of this quantity are subject to a large potential diurnal cycle including cool skin layer effects (especially at night under clear skies and low wind speed conditions) and warm layer effects in the daytime. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The sea surface subskin temperature is the temperature at the base of the conductive laminar sub-layer of the ocean surface, that is, at a depth of approximately 1 - 1.5 millimeters below the air-sea interface. For practical purposes, this quantity can be well approximated to the measurement of surface temperature by a microwave radiometer operating in the 6 - 11 gigahertz frequency range, but the relationship is neither direct nor invariant to changing physical conditions or to the specific geometry of the microwave measurements. Measurements of this quantity are subject to a large potential diurnal cycle due to thermal stratification of the upper ocean layer in low wind speed high solar irradiance conditions.

       <description>Sea surface temperature is usually abbreviated as &quot;SST&quot;. It is the temperature of sea water near the surface (including the part under sea-ice, if any). More specific terms, namely sea_surface_skin_temperature, sea_surface_subskin_temperature, and surface_temperature are available for the skin, subskin, and interface temperature. respectively. For the temperature of sea water at a particular depth or layer, a data variable of sea_water_temperature with a vertical coordinate axis should be used. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The wave direction in each frequency band, calculated from the second-order components of the wave directional spectrum. Since there is an ambiguity of 180 degrees in the calculation of Alpha2 (i.e. 90 degrees and 270 degrees result in equivalent spectra), the value closer to Alpha1 is selected. The full directional wave spectrum is described as a Fourier series: S = a0/2 + a1cos(theta) + b1sin(theta) + a2cos(2theta) + b2sin(2theta). The Fourier coefficients a1, b1, a2, &amp; b2 can be converted to polar coordinates as follows: R1 = (SQRT(a1a1+b1b1))/a0, R2 = (SQRT(a2a2+b2b2))/a0, ALPHA1 = 270.0-ARCTAN(b1,a1), ALPHA2 = 270.0-(0.5*ARCTAN(b2,a2)+{0 or 180, whichever minimizes the difference between ALPHA1 and ALPHA2}). ALPHA2 is the principal wave direction, which is determined from the second-order Fourier coefficients. This spectral parameter is a separate quantity from the bulk parameter (MWDIR), which has the standard name sea_surface_wave_from_direction_at_variance_spectral_density_maximum. The phrase &quot;from_direction&quot; is used in the construction X_from_direction and indicates the direction from which the velocity vector of X is coming. The direction is a bearing in the usual geographical sense, measured positive clockwise from due north.</description>

       <description>Absolute Salinity, S_A, is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the Intergovernmental Oceanographic Commission (IOC). It is the mass fraction of dissolved material in sea water. Absolute Salinity incorporates the spatial variations in the composition of sea water. This type of Absolute Salinity is also called &quot;Density Salinity&quot;. TEOS-10 estimates Absolute Salinity as the salinity variable that, when used with the TEOS-10 expression for density, yields the correct density of a sea water sample even when the sample is not of Reference Composition. In practice, Absolute Salinity is often calculated from Practical Salinity using a spatial lookup table of pre-defined values of the Absolute Salinity Anomaly. It is recommended that the version of (TEOS-10) software and the associated Absolute Salinity Anomaly climatology be specified within metadata by attaching a comment attribute to the data variable. Reference: www.teos-10.org; Millero et al., 2008 doi: 10.1016/j.dsr.2007.10.001. There are also standard names for the precisely defined salinity quantities sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 onwards), sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity.</description>

The surface flux is expressed as a heat flux and converted to a passive tracer increment as if it were a heat flux being added to conservative temperature. The passive tracer is transported within the ocean as if it were conservative temperature. The passive tracer is zero in the control climate of the model. The passive tracer records added heat, as described for the CMIP6 FAFMIP experiment (doi:10.5194/gmd-9-3993-2016), following earlier ideas. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_water_specific_potential_enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the &quot;heat content&quot; of sea water, by a factor of one hundred, than is potential temperature.

       <description>Cox Salinity, S_C, is defined unitless as a mass fraction per mil (0/00) or &quot;parts per thousand&quot;. S_C was the standard salinity measure from 1967 until Practical Salinity, S_P, was established with PSS-78 (1978). Chlorinity, Cl, is calculated from the conductivity of a sea water sample and since the work of the Joint Panel for Oceanographic Tables and Standards (JPOTS; 1966) is converted into Cox Salinity using S_C = 1.80655Cl. This type of salinity was called simply &quot;salinity&quot; from 1967 to 1978. Cox Salinity was replaced by Practical Salinity in 1978. Cox Salinity is converted to Practical Salinity following S_P = S_C, however the accuracy of this is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of the Practical Salinity Scale 1978 (PSS-78).

       <description>Knudsen Salinity, S_K, is defined unitless as a mass fraction per mil (0/00) or &quot;parts per thousand&quot;, and was calculated from the titration of inorganic salts from a sample of sea water after a commission to study the problem of determining salinity and density was initiated by the International Council for the Exploration of the Sea (ICES) in 1899. S_K was the standard salinity measure until S_C (Cox Salinity) was established in 1967. Since the work of Knudsen (1901), chlorinity is converted into Knudsen Salinity using S_K = 0.030 + 1.805 Cl. This type of salinity was called simply &quot;salinity&quot; from 1901 to 1966. From the 1960s on, electrical conductivity began to be used to estimate the Knudsen Salinity, rather than chemical titration. Knudsen Salinity was replaced by Cox Salinity in 1967 which was in turn replaced by Practical Salinity, S_P, in 1978. Conversion of Knudsen Salinity to Practical Salinity follows S_P = (S_K - 0.03) * (1.80655 / 1.805).

       <description>&quot;Neutral density&quot; is a variable designed so that a surface of constant neutral density everywhere has a local slope that is close to the local slope of the neutral tangent plane. At the sea surface in the equatorial Pacific neutral density is very close to the potential density anomaly. At other locations, this is not the case. For example, along a neutral density surface there is a difference of up to 0.14 kg/m^3 in the potential density anomaly at the outcrops in the Southern and Northern hemispheres.

If no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is sea water the integral is assumed to be calculated over the full depth of the ocean.

The subduction and subsequent transport of surface water carry into the interior ocean considerable quantities of alkalinity, which is entirely independent of biological activity (such as organic decomposition and oxidation) after the water leaves the sea surface. Such alkalinity is termed “preformed” alkalinity (Redfield,1942).</description>

The passive tracer is initialised to the conservative temperature in the control climate before the perturbation is imposed. Its surface flux is the heat flux from the atmosphere, not including the imposed perturbation, and is converted to a passive tracer increment as if it were being added to conservative temperature. The passive tracer is transported within the ocean as if it were conservative temperature. The passive tracer records redistributed heat, as described for the CMIP6 FAFMIP experiment (doi:10.5194/gmd-9-3993-2016), following earlier ideas. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_water_specific_potential_enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the &quot;heat content&quot; of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

       <description>Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966),  sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

       <description>The salinity at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model and within the benthic boundary layer for measurements. Sea water salinity is the salt concentration of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity.

       <description>Sea water temperature is the in situ temperature of the sea water. To specify the depth at which the temperature applies use a vertical coordinate variable or scalar coordinate variable. There are standard names for sea_surface_temperature, sea_surface_skin_temperature, sea_surface_subskin_temperature and sea_surface_foundation_temperature which can be used to describe data located at the specified surfaces. For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard &quot;scales&quot;. These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C). The International Equation of State of Seawater 1980 (EOS-80, UNESCO, 1981) and the Practical Salinity Scale (PSS-78) were both based on IPTS-68, while the Thermodynamic Equation of Seawater 2010 (TEOS-10) is based on ITS-90.

It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

Local zenith is a line perpendicular to the Earth&#x27;s surface at a given location. &quot;Observation target&quot; means a location on the Earth defined by the sensor performing the observations.  A standard name also exists for platform_zenith_angle, where &quot;platform&quot; refers to the vehicle from which observations are made e.g. aeroplane, ship, or satellite. For some viewing geometries the sensor and the platform cannot be assumed to be close enough to neglect the difference in calculated zenith angle.</description>

       <description>&quot;Single scattering albedo&quot; is the fraction of radiation in an incident light beam scattered by the particles of an aerosol reference volume for a given wavelength. It is the ratio of the scattering and the extinction coefficients of the aerosol particles in the reference volume. A coordinate variable with a standard name of radiation_wavelength or radiation_frequency should be included to specify either the wavelength or frequency. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. &quot;Ambient_aerosol&quot; means that the aerosol is measured or modelled at the ambient state of pressure, temperature and relative humidity that exists in its immediate environment. &quot;Ambient aerosol particles&quot; are aerosol particles that have taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the particles. To specify the relative humidity and temperature at which the quantity described by the standard name applies, provide scalar coordinate variables with standard names of &quot;relative_humidity&quot; and &quot;air_temperature&quot;. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.</description>

       <description>The phrase &quot;square_of_X&quot; means X*X. &quot;Height_above_X&quot; means the vertical distance above the named surface X. &quot;Sea surface height&quot; is a time-varying quantity. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean). In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. To specify which geoid or geopotential datum is being used as a reference level, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention. By definition of the geoid, the global average of the time-mean sea surface height (i.e. mean sea level) above the geoid must be zero.</description>

       <description>The phrase &quot;square_of_X&quot; means X*X. Sea surface salinity is the salt concentration of sea water close to the sea surface, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and the units attribute should normally be given as 1e-3 or 0.001 i.e. parts per thousand. Sea surface salinity is often abbreviated as &quot;SSS&quot;. For the salinity of sea water at a particular depth or layer, a data variable of &quot;sea_water_salinity&quot; or one of the more precisely defined salinities should be used with a vertical coordinate axis. There are standard names for the precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale. The unit &quot;parts per thousand&quot; was used for sea_water_knudsen_salinity and sea_water_cox_salinity.</description>

       <description>In thermodynamics and fluid mechanics, stagnation temperature is the temperature at a stagnation point in a fluid flow. At a stagnation point the speed of the fluid is zero and all of the kinetic energy has been converted to internal energy and is added to the local static enthalpy. In both compressible and incompressible fluid flow, the stagnation temperature is equal to the total temperature at all points on the streamline leading to the stagnation point. In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore, total air temperature is higher than the static (or ambient) air temperature. Total air temperature is an essential input to an air data computer in order to enable computation of static air temperature and hence true airspeed. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. To specify which area is quantified by a variable with standard name area_fraction, provide a coordinate variable or scalar coordinate variable with standard name area_type. Alternatively, if one is defined, use a more specific standard name of X_area_fraction for the fraction of horizontal area occupied by X. The cloud area fraction is for the whole atmosphere column, as seen from the surface or the top of the atmosphere. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). Cloud area fraction is also called &quot;cloud amount&quot; and &quot;cloud cover&quot;.</description>

       <description>In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. Stratiform precipitation, whether liquid or frozen, is precipitation that formed in stratiform cloud. Graupel consists of heavily rimed snow particles, often called snow pellets; often indistinguishable from very small soft hail except when the size convention that hail must have a diameter greater than 5 mm is adopted. Reference: American Meteorological Society Glossary http://glossary.ametsoc.org/wiki/Graupel. There are also separate standard names for hail. Standard names for &quot;graupel_and_hail&quot; should be used to describe data produced by models that do not distinguish between hail and graupel.</description>

       <description>The surface called &quot;surface&quot; means the lower boundary of the atmosphere. &quot;Diffuse&quot; radiation is radiation that has been scattered by gas molecules in the atmosphere and by particles such as cloud droplets and aerosols. The term &quot;shortwave&quot; means shortwave radiation. Hemispherical reflectance is the ratio of the energy of the reflected to the incident radiation. This term gives the fraction of the surface_diffuse_downwelling_shortwave_flux_in_air which is reflected. If the diffuse radiation is isotropic, this term is equivalent to the integral of surface_bidirectional_reflectance over all incident angles and over all outgoing angles in the hemisphere above the surface. A coordinate variable of radiation_wavelength or radiation_frequency can be used to specify the wavelength or frequency, respectively, of the radiation. Shortwave hemispherical reflectance is related to albedo, but albedo is defined in terms of the fraction of the full spectrum of incident solar radiation which is reflected. It is related to the hemispherical reflectance averaged over all wavelengths using a weighting proportional to the incident radiative flux.</description>

       <description>The surface called &quot;surface&quot; means the lower boundary of the atmosphere. &quot;Direct&quot; (also known as &quot;beam&quot;) radiation is radiation that has followed a direct path from the sun and is alternatively known as &quot;direct insolation&quot;. Downwelling radiation is radiation from above. It does not mean &quot;net downward&quot;. The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. The term &quot;shortwave&quot; means shortwave radiation. When thought of as being incident on a surface, a radiative flux is sometimes called &quot;irradiance&quot;. In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called &quot;vector irradiance&quot;. In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics.</description>

       <description>The surface called &quot;surface&quot; means the lower boundary of the atmosphere. &quot;Direct&quot; (also known as &quot;beam&quot;) radiation is radiation that has followed a direct path from the sun and is alternatively known as &quot;direct insolation&quot;. The term &quot;shortwave&quot; means shortwave radiation. Hemispherical reflectance is the ratio of the energy of the reflected to the incident radiation. This term gives the fraction of the surface_direct_downwelling_shortwave_flux_in_air which is reflected. It is equivalent to the surface_bidirectional_reflectance at the incident angle of the incoming solar radiation and integrated over all outgoing angles in the hemisphere above the surface. A coordinate variable of radiation_wavelength or radiation_frequency can be used to specify the wavelength or frequency, respectively, of the radiation. Shortwave hemispherical reflectance is related to albedo, but albedo is defined in terms of the fraction of the full spectrum of incident solar radiation which is reflected. It is related to the hemispherical reflectance averaged over all wavelengths using a weighting proportional to the incident radiation flux.</description>

       <description>The surface called &quot;surface&quot; means the lower boundary of the atmosphere. Downwelling radiation is radiation from above. It does not mean &quot;net downward&quot;. The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. &quot;Photosynthetic&quot; radiation is the part of the spectrum which is used in photosynthesis e.g. 400-700 nm. The range of wavelengths could be specified precisely by the bounds of a coordinate of radiation_wavelength. Spherical irradiance is the radiation incident on unit area of a hemispherical (or &quot;2-pi&quot;) collector. It is sometimes called &quot;scalar irradiance&quot;. The direction (up/downwelling) is specified. Radiation incident on a 4-pi collector has standard names of &quot;omnidirectional spherical irradiance&quot;.</description>

A velocity is a vector quantity. &quot;x&quot; indicates a vector component along the grid x-axis, positive with increasing x. &quot;Geostrophic&quot; indicates that geostrophic balance is assumed, i.e. that the pressure gradient force and the Coriolis force are balanced and the large scale fluid flow is parallel to the isobars. &quot;Mean sea level&quot; means the time mean of sea surface elevation at a given location over an arbitrary period sufficient to eliminate the tidal signals. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. (The volume enclosed between the geoid and the sea floor equals the mean volume of water in the ocean.) In an ocean GCM the geoid is the surface of zero depth, or the rigid lid if the model uses that approximation. The quantity with standard name surface_geostrophic_sea_water_x_velocity_assuming_mean_sea_level_for_geoid is the variable part of surface_geostrophic_sea_water_x_velocity. The assumption that sea level is equal to the geoid means that the stationary component of ocean circulation is equal to zero.</description>

       <description>The surface called &quot;surface&quot; means the lower boundary of the atmosphere. The phrase &quot;ratio_of_X_to_Y&quot; means X/Y. Upwelling radiation is radiation from below. It does not mean &quot;net upward&quot;. Downwelling radiation is radiation from above. It does not mean &quot;net downward&quot;. The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. Radiance is the radiative flux in a particular direction, per unit of solid angle. The direction towards which it is going must be specified, for instance with a coordinate of angle_of_emergence. Radiative flux is the sum of shortwave and longwave radiative fluxes. When thought of as being incident on a surface, a radiative flux is sometimes called &quot;irradiance&quot;. In relation to satellite ocean color products the quantity named surface_ratio_of_upwelling_radiance_emerging_from_sea_water_to_downwelling_radiative_flux_in_air is sometimes called &quot;remote sensing reflectance&quot; and has a bidirectional dependence. The direction of the downwelling flux can be specified using a coordinate with the standard name angle_of_incidence.</description>

The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Plant respiration is the sum of respiration by parts of plants both above and below the soil. Plants which photosynthesise are autotrophs i.e. &quot;producers&quot; of the biomass which they respire from inorganic precursors using sunlight for energy. The stem of a plant is the axis that bears buds and shoots with leaves and, at its basal end, roots. Its function is to carry water and nutrients. Examples include the stalk of a plant or the main trunk of a tree.</description>

It is often called the lifted index (LI) and provides a measure of the instability of the atmosphere. The air parcel is &quot;lifted&quot; by moving the air parcel from the starting air pressure to the Lifting Condensation Level (dry adiabatically) and then from the Lifting Condensation Level to the finishing air pressure (wet adiabatically). Air temperature is the bulk temperature of the air.

The quantity with standard name temperature_flux_due_to_evaporation_expressed_as_heat_flux_out_of_sea_water is the heat energy carried by the transfer of water away from the liquid ocean through the process of evaporation.  It is distinct from the transfer of latent heat and is calculated relative to the heat that would be transported by water evaporating at zero degrees Celsius. It is calculated as the product QevapCpTevap, where Qevap is the mass flux of evaporating water (kg m-2 s-1), Cp is the specific heat capacity of water and Tevap is the temperature in degrees Celsius of the evaporating water. In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics.

       <description>The quantity with standard name temperature_flux_due_to_runoff_expressed_as_heat_flux_into_sea_water is the heat carried by the transfer of water into the liquid ocean by the process of runoff. This quantity additionally includes melt water from sea ice and icebergs. It is calculated relative to the heat that would be transported by runoff water entering the sea at zero degrees Celsius. It is calculated as the product QrunoffCpTrunoff, where Q runoff is the mass flux of liquid runoff entering the sea water (kg m-2 s-1), Cp is the specific heat capacity of water, and Trunoff is the temperature in degrees Celsius of the runoff water. In accordance with common usage in geophysical disciplines, &quot;flux&quot; implies per unit area, called &quot;flux density&quot; in physics. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Runoff is the liquid water which drains from land. If not specified, &quot;runoff&quot; refers to the sum of surface runoff and subsurface drainage.</description>

       <description>The temperature at any given depth (or in a layer) below the surface of the ground, excluding surficial snow and ice (but not permafrost or soil). For temperatures in surface lying snow and ice, the more specific standard names temperature_in_surface_snow and land_ice_temperature should be used. For temperatures measured or modelled specifically for the soil layer (the near-surface layer where plants sink their roots) the standard name soil_temperature should be used. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The temperature_of_analysis_of_sea_water is the reference temperature for the effects of temperature on the measurement of another variable. This temperature should be measured, but may have been calculated, or assumed. For example, the temperature of the sample when measuring pH, or the temperature of equilibration in the case of dissolved gases. The linkage between the data variable and the variable with a standard_name of temperature_of_analysis_of_sea_water is achieved using the ancillary_variables attribute on the data variable.

It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The phrase &quot;tendency_of_X&quot; means derivative of X with respect to time. &quot;Content&quot; indicates a quantity per unit area. The &quot;atmosphere content&quot; of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including &quot;content_of_atmosphere_layer&quot; are used. The mass is the total mass of the particles. &quot;Aerosol&quot; means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. &quot;Dry aerosol particles&quot; means aerosol particles without any water uptake. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. &quot;Emission&quot; means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. the surface of the earth). &quot;Emission&quot; is a process entirely distinct from &quot;re-emission&quot; which is used in some standard names.</description>

       <description>&quot;tendency_of_X&quot; means derivative of X with respect to time. &quot;Content&quot; indicates a quantity per unit area. The &quot;atmosphere content&quot; of a quantity refers to the vertical integral from the surface to the top of the atmosphere. For the content between specified levels in the atmosphere, standard names including &quot;content_of_atmosphere_layer&quot; are used. The mass is the total mass of the molecules. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. &quot;Emission&quot; means emission from a primary source located anywhere within the atmosphere, including at the lower boundary (i.e. earth&#x27;s surface). &quot;Emission&quot; is a process entirely distinct from &quot;re-emission&quot; which is used in some standard names. Ethers are a class of organic compounds that contain an ether group - an oxygen atom connected to two alkyl or aryl groups - of general formula R-O-R. In standard names &quot;ethers&quot; is the term used to describe the group of ether species that are represented within a given model. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. The &quot;agricultural production&quot; sector comprises the agricultural processes of enteric fermentation, manure management, rice cultivation, agricultural soils and other. It may also include any not-classified or &quot;other&quot; combustion, which is commonly included in agriculture-related inventory data. &quot;Agricultural production&quot; is the term used in standard names to describe a collection of emission sources. A variable which has this value for the standard_name attribute should be accompanied by a comment attribute which lists the source categories and provides a reference to the categorization scheme, for example, &quot;IPCC (Intergovernmental Panel on Climate Change) source categories 4A, 4B, 4C, 4D and 4G as defined in the 2006 IPCC guidelines for national greenhouse gas inventories&quot;.</description>

       <description>The phrase &quot;tendency_of_X&quot; means derivative of X with respect to time. &quot;Eastward&quot; indicates a vector component which is positive when directed eastward (negative westward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name &quot;upward_air_velocity&quot;). The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. The &quot;Transformed Eulerian Mean&quot; refers to a formulation of the mean equations which incorporates some eddy terms into the definition of the mean, described in Andrews et al (1987): Middle Atmospheric Dynamics.

       <description>Global average sea level change is due to change in volume of the water in the ocean, caused by mass and/or density change, or to change in the volume of the ocean basins, caused by tectonics etc. It is sometimes called &quot;eustatic&quot;, which is a term that also has other definitions. It differs from the change in the global average sea surface height relative to the centre of the Earth by the global average vertical movement of the ocean floor. Zero sea level change is an arbitrary level. &quot;tendency_of_X&quot; means derivative of X with respect to time. Because global average sea level change quantifies the change in volume of the world ocean, it is not calculated necessarily by considering local changes in mean sea level.</description>

Aerosol takes up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the aerosol. &quot;Dry aerosol particles&quot; means aerosol particles without any water uptake. The &quot;aviation&quot; sector includes fuel combustion activities related to civil aviation. &quot;Aviation&quot; is the term used in standard names to describe a collection of emission sources. A variable which has this value for the standard_name attribute should be accompanied by a comment attribute which lists the source categories and provides a reference to the categorization scheme, for example, &quot;IPCC (Intergovernmental Panel on Climate Change) source category 1A3a as defined in the 2006 IPCC guidelines for national greenhouse gas inventories&quot;. Chemically, &quot;elemental carbon&quot; is the carbonaceous fraction of particulate matter that is thermally stable in an inert atmosphere to high temperatures near 4000K and can only be gasified by oxidation starting at temperatures above 340 C. It is assumed to be inert and non-volatile under atmospheric conditions and insoluble in any solvent (Ogren and Charlson, 1983).</description>

Sublimation is the conversion of solid into vapor. Deposition is the opposite of sublimation, i.e. it is the conversion of vapor into solid.  Deposition is distinct from the processes of dry deposition and wet deposition of atmospheric aerosol particles, which are referred to in some standard names. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes).  The specification of a physical process by the phrase due_to_process means that the quantity named is a  single term in a sum of terms which together compose the general quantity  named by omitting the phrase.  &quot;tendency_of_X&quot; means derivative of X with respect to time.</description>

The atmospheric boundary layer is typically characterised by a well-mixed sub-cloud layer of order 500 metres, and by a more extended conditionally unstable layer with boundary-layer clouds up to 2 km.

In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). &quot;Cloud liquid water&quot; refers to the liquid phase of cloud water. A diameter of 0.2 mm has been suggested as an upper limit to the size of drops that shall be regarded as cloud drops; larger drops fall rapidly enough so that only very strong updrafts can sustain them. Any such division is somewhat arbitrary, and active cumulus clouds sometimes contain cloud drops much larger than this. Reference: AMS Glossary http://glossary.ametsoc.org/wiki/Cloud_drop.

       <description>The phrase &quot;tendency_of_X&quot; means derivative of X with respect to time. This tendency encompasses all processes that impact on the time changes for the heat content within a grid cell. The phrase &quot;expressed_as_heat_content&quot; means that this quantity is calculated as the specific heat capacity times density of sea water multiplied by the conservative temperature of the sea water in the grid cell and integrated over depth. If used for a layer heat content, coordinate bounds should be used to define the extent of the layers. If no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is sea water the integral is assumed to be calculated over the full depth of the ocean. Conservative Temperature is defined as part of the Thermodynamic Equation of Seawater 2010 (TEOS-10) which was adopted in 2010 by the International Oceanographic Commission (IOC). Conservative Temperature is specific potential enthalpy (which has the standard name sea_water_specific_potential_enthalpy) divided by a fixed value of the specific heat capacity of sea water, namely cp_0 = 3991.86795711963 J kg-1 K-1. Conservative Temperature is a more accurate measure of the &quot;heat content&quot; of sea water, by a factor of one hundred, than is potential temperature. Because of this, it can be regarded as being proportional to the heat content of sea water per unit mass.

The phrase &quot;expressed_as_heat_content&quot; means that this quantity is calculated as the specific heat capacity times density of sea water multiplied by the potential temperature of the sea water in the grid cell and integrated over depth. If used for a layer heat content, coordinate bounds should be used to define the extent of the layers. If no coordinate bounds are specified, it is assumed that the integral is calculated over the entire vertical extent of the medium, e.g, if the medium is sea water the integral is assumed to be calculated over the full depth of the ocean. Potential temperature is the temperature a parcel of air or sea water would have if moved adiabatically to sea level pressure. The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. &quot;Dianeutral mixing&quot; means mixing across surfaces of neutral buoyancy. &quot;Parameterized&quot; means the part due to a scheme representing processes which are not explicitly resolved by the model.</description>

       <description>&quot;tendency_of_X&quot; means derivative of X with respect to time. Sea water salinity is the salt content of sea water, often on the Practical Salinity Scale of 1978. However, the unqualified term &#x27;salinity&#x27; is generic and does not necessarily imply any particular method of calculation. The units of salinity are dimensionless and normally given as 1e-3 or 0.001 i.e. parts per thousand. There are standard names for the more precisely defined salinity quantities: sea_water_knudsen_salinity, S_K (used for salinity observations between 1901 and 1966), sea_water_cox_salinity, S_C (used for salinity observations between 1967 and 1977), sea_water_practical_salinity, S_P (used for salinity observations from 1978 to the present day), sea_water_absolute_salinity, S_A, sea_water_preformed_salinity, S_*, and sea_water_reference_salinity. Practical Salinity is reported on the Practical Salinity Scale of 1978 (PSS-78), and is usually based on the electrical conductivity of sea water in observations since the 1960s. Conversion of data between the observed scales follows: S_P = (S_K - 0.03) * (1.80655 / 1.805) and S_P = S_C, however the accuracy of the latter is dependent on whether chlorinity or conductivity was used to determine the S_C value, with this inconsistency driving the development of PSS-78. The more precise standard names should be used where appropriate for both modelled and observed salinities. In particular, the use of sea_water_salinity to describe salinity observations made from 1978 onwards is now deprecated in favor of the term sea_water_practical_salinity which is the salinity quantity stored by national data centers for post-1978 observations. The only exception to this is where the observed salinities are definitely known not to be recorded on the Practical Salinity Scale.

McWilliams 2016, Submesoscale currents in the ocean, Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, volume 472, issue 2189. DOI: 10.1098/rspa.2016.0117. Parameterized mesoscale eddy advection is represented in ocean models using schemes such as the Gent-McWilliams scheme. There are also standard names for parameterized_submesoscale_eddy_advection which, along with parameterized_mesoscale_eddy_advection, contributes to the total parameterized eddy advection. Additionally, when the parameterized advective process is represented in the model as a skew-diffusion rather than an advection, then the parameterized skew diffusion should be included in this diagnostic. The convergence of a skew-flux is identical (in the continuous formulation) to the convergence of an advective flux, making their tendencies the same.</description>

For observed data, depending on the period during which the observation was made, the measured in situ temperature was recorded against standard &quot;scales&quot;. These historical scales include the International Practical Temperature Scale of 1948 (IPTS-48; 1948-1967), the International Practical Temperature Scale of 1968 (IPTS-68, Barber, 1969; 1968-1989) and the International Temperature Scale of 1990 (ITS-90, Saunders 1990; 1990 onwards). Conversion of data between these scales follows t68 = t48 - (4.4 x 10e-6) * t48(100 - t - 48); t90 = 0.99976 * t68. Observations made prior to 1948 (IPTS-48) have not been documented and therefore a conversion cannot be certain. Differences between t90 and t68 can be up to 0.01 at temperatures of 40 C and above; differences of 0.002-0.007 occur across the standard range of ocean temperatures (-10 - 30 C).

       <description>toa_brightness_temperature_bias_at_standard_scene_due_to_intercalibration is the difference between top-of-atmosphere (TOA) brightness temperature of the reference sensor and TOA brightness temperature of the monitored sensor. This TOA brightness temperature difference is a measure of the calibration difference between the monitored and reference sensors. The standard scene is a target area with typical Earth surface and atmospheric conditions that is accepted as a reference. Brightness temperature of a body is the temperature of a black body which radiates the same power per unit solid angle per unit area at a given wavenumber. TOA brightness temperature of the standard scene is calculated using a radiative transfer simulation for a given viewing geometry. The resultant top-of-atmosphere spectral radiance is then integrated with each sensor&#x27;s spectral response function and converted to equivalent brightness temperature. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. It is strongly recommended that a variable with this standard name should have the attribute units_metadata=&quot;temperature: difference&quot;, meaning that it refers to temperature differences and implying that the origin of the temperature scale is irrelevant, because it is essential to know whether a temperature is on-scale or a difference in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>The abbreviation &quot;toa&quot; means top of atmosphere. Radiance is the radiative flux in a particular direction, per unit of solid angle. The direction towards which it is going must be specified, for instance with a coordinate of zenith_angle. A coordinate variable for radiation wavelength should be given the standard name radiation_wavelength. The specification of a physical process by the phrase &quot;due_to_&quot; process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. Some of the solar energy absorbed by pigment systems of plant leaves during photosynthesis is re-emitted as fluorescence. This is called solar-induced chlorophyll fluorescence (SIF). It is a radiance that can be measured on a global scale at various wavelengths and by multiple space borne instruments. SIF is considered a measurement of the photosynthetic machinery in plants and can provide a direct approach for the diagnosis of the actual functional status of vegetation. It is therefore considered a functional proxy of terrestrial gross primary productivity which has the standard name gross_primary_productivity_of_biomass_expressed_as_carbon. SIF spans the wavelength range 600 - 800 nm.</description>

       <description>The &quot;Ultraviolet Index&quot; (UVI) is a measure of the amount of solar ultraviolet radiation that reaches the surface of the earth depending on factors such as time of day and cloud cover. It is often used to alert the public of the need to limit sun exposure and use sun creams to protect the skin. Each point on the Index scale is equivalent to 25 mW m-2 of UV radiation (reference: Australian Bureau of Meteorology, http://www.bom.gov.au/uv/about_uv_index.shtml). The UVI range is expressed as a numeric value from 0 to 20 and sometimes graphically as bands of color indicating the attendant risk of skin damage. A UVI of 0-2 is described as &#x27;Low&#x27; (represented graphically in green); a UVI of 11 or greater is described as &quot;Extreme&quot; (represented graphically in purple). The higher the UVI, the greater the potential health risk to humans and the less time it takes for harm to occur. To specify the amount of cloud cover at which the data variable applies, provide a scalar coordinate variable with standard name &quot;cloud_area_fraction&quot;. Standard names are also defined for the quantities ultraviolet_index_assuming_clear_sky and ultraviolet_index_assuming_overcast_sky.</description>

The phrase &quot;from_direction&quot; is used in the construction X_from_direction and indicates the direction from which the velocity vector of X is coming. The direction is a bearing in the usual geographical sense, measured positive clockwise from due north. In meteorological reports, the direction of the wind vector is usually (but not always) given as the direction from which it is blowing (&quot;wind_from_direction&quot;) (westerly, northerly, etc.). In other contexts, such as atmospheric modelling, it is often natural to give the direction in the usual manner of vectors as the heading or the direction to which it is blowing (&quot;wind_to_direction&quot;) (eastward, southward, etc.).

The sign convention is that &quot;upwelling&quot; is positive upwards and &quot;downwelling&quot; is positive downwards. The term &quot;shortwave&quot; means shortwave radiation. When thought of as being incident on a surface, a radiative flux is sometimes called &quot;irradiance&quot;. In addition, it is identical with the quantity measured by a cosine-collector light-meter and sometimes called &quot;vector irradiance&quot;.

       <description>&quot;Area fraction&quot; is the fraction of a grid cell&#x27;s horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. &quot;where sea_ice&quot;), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. &quot;Vegetation&quot; means any plants e.g. trees, shrubs, grass. The term &quot;plants&quot; refers to the kingdom of plants in the modern classification which excludes fungi.

It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values &quot;on-scale&quot; or &quot;difference&quot;, whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).</description>

       <description>&quot;Content&quot; indicates a quantity per unit area. &quot;Wood debris&quot; means dead organic matter composed of coarse wood. It is distinct from fine litter. The precise distinction between &quot;fine&quot; and &quot;coarse&quot; is model dependent. The sum of the quantities with standard names wood_debris_mass_content_of_nitrogen, surface_litter_mass_content_of_nitrogen and subsurface_litter_mass_content_of_nitrogen is the total nitrogen mass content of dead plant material.</description>

Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) A gust is a sudden brief period of high wind speed. In an observed timeseries of wind speed, the gust wind speed can be indicated by a cell_methods of maximum for the time-interval. In an atmospheric model which has a parametrised calculation of gustiness, the gust wind speed may be separately diagnosed from the wind speed.</description>

    The highlights for this major/minor release of Iris include:
 
-   * N/A
+   * Iris now supports Python version 3.13, and has dropped support for Python 3.10,
+     as per the Scientific Python
+     `SPEC 0 <https://scientific-python.org/specs/spec-0000/>`_ schedule.
+
+   * Data is now optional in a cube, which can simplify the regridding process and lay
+     the ground work for future features.  See :issue:`4447`.
+
+   * Added :data:`iris.loading.LOAD_PROBLEMS` to capture objects which could not be
+     loaded correctly, to assist in fixing loading problems via the Iris API. Several
+     loading operations no longer raise their own warnings; instead their loading
+     problems are captured in the common object, and a single generic warning is raised.
+     See :class:`iris.loading.LoadProblems`.
+
+   * Extended the features of :class:`iris.LoadPolicy` and :data:`iris.LOAD_POLICY`,
+     which are now renamed to :class:`iris.CombineOptions` and
+     :data:`iris.COMBINE_POLICY` respectively, and gave access to the mechanism in the
+     new :func:`iris.util.combine_cubes` utility.
+
+   * Added two new utility functions, :func:`iris.util.combine_cubes` and
+     :meth:`iris.util.equalise_cubes`, to assist with merge/concatenate, as well as
+     other features to improve loading control.
+
+   Checkout the performance enhancements section for an array of improvements to the
+   performance of Iris. Special thanks to the ESMValTool devs for these contributions.
 
    And finally, get in touch with us on :issue:`GitHub<new/choose>` if you have
    any issues or feature requests for improving Iris. Enjoy!

+#     - enable user to build locally, as well as in CI

+#    - *no* "prune" command is used
+#    - use "include-recursive", by relevant file extensions

+#     - default package rules mean we generally don't actually *need* a statement

 #. `@HGWright`_ added a new warning to inform users that the boolean coordinate generated by
    :meth:`iris.coord_categorisation.add_season_membership` is not saveable to netcdf. (:pull:`6305`)
 
+#. `@bouweandela`_ changed the ``convert_units`` method on cubes and coordinates

Subject: [PATCH 72/90] Allow masked data in coords (#6468)

* Allow masked data to be passed into a Cell, and by extensions a Coord.

* Handled case where integer array with masked values could not be created.

* Handle case where reading of scalar masked value from netCDF file
looses the original dtype.

* Removed some comments

* Removed fill_value keyword to masked_array creation - wasn't fixing the
issue with numpy warnings about NaNs.

* Single method for handling points arrays with masked data

* Refactored to add small inline helper function to add AuxCoord

* Refactored the masked array handling and now filling masked arrays with default fill type.

* Added test for Cell hashing

* test_Cell.py: Converted unittest to pytest

* Added tests for merging of scalar aux coords with mising data.

* Removed unnecessary __main__ entry point from test_Cell.py

* Missing hash test for bounded points

* More rigorous test on masked data of merged AuxCoord

* Migrated test_merge.py to pytest.

* Moved tests/test_merge.py to tests/unit/merge/test_merge.py

* What's new entry.

* Fixed some typos in comment

* Split out integration test from unit/merge/test_merge.py to
integration/merge/test_merge.py
