Great to have the capability for ingesting satwnd.bufr.

TYPE: new feature KEYWORDS: WRFDA, satwnd.bufr SOURCE: Jamie Bresch (NCAR) DESCRIPTION OF CHANGES: When ob_format=1 (bufr), WRFDA reads NCEP's prepbufr file and processes satellite winds (AMV) contained in prepbufr as ob type geoamv. This PR adds the capability to read a separate satwnd bufr file and decode additional AMVs (as ob type polaramv) that are not included in prepbufr. The `use_satwnd_bufr` default is true, when `ob_format=1` and `satwnd.bufr` does not exist in the working directory. There is no impact except for a warning message of "satwnd.bufr does not exist".

Superobbing is available when `thin_conv_opt` (polaramv) is set to 3 (2-D thinning boxes) or 4 (3-D thinning boxes). The reading of an external obs error table is moved one level up, so the table values can be used by both da_read_obs_bufr.inc and da_read_obs_bufr_satwnd.inc Piggybacking on top of this PR are some other README.namelist update to fix a few typos pointed out by Yi-Chuan Lo (Central Weather Bureau, Taiwan) and adding a descrption for recently added gpsref options.

DESCRIPTION OF CHANGES:
When ob_format=1 (bufr), WRFDA reads NCEP's prepbufr file and processes satellite winds (AMV) contained in prepbufr
as ob type geoamv. This PR adds the capability to read a separate satwnd bufr file and decode additional AMVs (as
ob type polaramv) that are not included in prepbufr.
The
use_satwnd_bufrdefault is true, whenob_format=1andsatwnd.bufrdoes not exist in the working directory.There is no impact except for a warning message of "satwnd.bufr does not exist".
Data sources:
https://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gdas.YYYYMMDD/HH/atmos/gdas.tHHz.satwnd.tm00.bufr_d
cheyenne:/gpfs/fs1/collections/rda/data/ds351.0/bufr/YYYY/gdas.satwnd.tHHz.YYYYMMDD.bufr
Thinning for satwnd.bufr (done in da_read_obs_bufr_satwnd.inc) is implemented differently than all other ob types.
Superobbing is available when
thin_conv_opt(polaramv) is set to 3 (2-D thinning boxes) or 4 (3-D thinning boxes).The reading of an external obs error table is moved one level up, so the table values can be used by both
da_read_obs_bufr.inc and da_read_obs_bufr_satwnd.inc
Piggybacking on top of this PR are some other README.namelist update to fix a few typos pointed out by Yi-Chuan Lo
(Central Weather Bureau, Taiwan) and adding a descrption for recently added gpsref options.
