Testing

How were these changes tested? The RTs provided by UFS Weather model were run.
What compilers / HPCs was it tested with? It is tested with both Intel and GNU compilers on NCAR's Cheyenne platform
Are the changes covered by regression tests? (If not, why? Do new tests need to be added?) Yes. Three new regression tests are added.

  • datm_cdeps_lnd_gswp3: 1 day run with CDEPS GSWP3 dataset

  • datm_cdeps_lnd_gswp3_rst: restart run with CDEPS GSWP3 dataset

  • control_p8_atmlnd_sbs: side-by-side test with active atmosphere, uses same configuration with control_p8 and the interaction with FV3 is uni-directional to allow comparing the results coming from FV3/CCPP/NOAHMP with external NOAHMP component.

  • Have the ufs-weather-model regression test been run? On what platform? Yes. Cheyyene

  • Will the code updates change regression test baseline? If yes, why? Please show the baseline directory below.
    There is not answer change but there is an issue with the input files of control_p8 which is explained in here in a detailed way.

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

Dependencies

If testing this branch requires non-default branches in other repositories, list them.
Those branches should have matching names (ideally)
