new global_nest_v1 suite and #715

[SamuelTrahanNOAA]

Description

This is a suite of physics schemes nominally planned for the RRFS v2 upgrade. It's being used for the Water in the West project to simulate atmospheric rivers using a global model with a static nest. Hence "global_nest_v1."

PR #715 is included by request of the UFS code managers.

Issue(s) addressed

• closes Updates to C3 and SAS convection schemes #715

Testing

How were these changes tested?

The suite was tested with a simulation of a February 24, 2023 atmospheric river event.

What compilers / HPCs was it tested with?

Hera intel. FV3 nesting does not work with the gnu compiler or in debug mode due to known issues.

Are the changes covered by regression tests? (If not, why? Do new tests need to be added?)

Yes. There are two new tests:

1. gnv1_c96_no_nest_debug - The standard C96 initial conditions used for most physics suites, configured to run global_nest_v1. This is run in debug mode for both compilers
2. gnv1_nested - Run off of the HAFS global static nest test initial conditions, this tests the suite in a static nest.

Have the ufs-weather-model regression test been run? On what platform?

Hera and Jet.

Will the code updates change regression test baseline? If yes, why? Please show the baseline directory below.

No. It adds two tests, but no tests change.

Please commit the regression test log files in your ufs-weather-model branch

Okay.
