Commit Queue Requirements:

• Fill out all sections of this template.
• N/A - No subcomponent changes. All sub component pull requests have been reviewed by their code managers.
• N/A - Change is at ufs-weather-model level only, and only affects one test. To avoid wasting resources, I've skipped all other tests. Run the full Intel+GNU RT suite (compared to current baselines) on either Hera/Derecho/Hercules
• N/A - See above Commit 'test_changes.list' from previous step

Description:

This draft PR replaces the gnv1_nested regression test with a new one that uses the Water in the West domain at C96 resolution. It uses input.nml and model_configure templates which are compatible with the global workflow.

IMPORTANT: When running the new regression test, you must use its new input data.

• INPUTDATA_ROOT=/scratch2/BMC/wrfruc/Samuel.Trahan/westwater/regtest-C96-guoqing/RT/NEMSfv3gfs/input-data-20240501

• NOTE TO SELF: Need variables in &surf_map_nml to support the global-workflow. Defaults can be found here: FV3/atmos_cubed_sphere/tools/fv_surf_map.F90

Changes

Regression Test Changes (Please commit test_changes.list):

• PR Updates/Changes Baselines.

Only the gnv1_nested regression test is affected, so I haven't run the full regression test suite.

Input data Changes:

• New input data.

Input data is here:

HERA: /scratch2/BMC/wrfruc/Samuel.Trahan/westwater/regtest-C96-guoqing/RT/NEMSfv3gfs/input-data-20240501

The only new files are in these subdirectories:

• FV3_input_data/INPUT_L127_nested/ - INPUT/ directory for gnv1_nested test
• FV3_fix_tiled/C96-nested - Tiled static files for rotated globe and its nest

Library Changes/Upgrades:

• No Updates

Testing Log:

• RDHPCS
  • Hera
  • Orion
  • Hercules
  • Jet
  • Gaea
  • Derecho
• WCOSS2
  • Dogwood/Cactus
  • Acorn
• CI
• opnReqTest (complete task if unnecessary)

This PR was a draft for a while due to model instability. After much experimenting and digging, I found this was the problem:

full_zs_filter = .true.

It must be:

full_zs_filter = .false.

With that change, the new test is stable and we can move forward with the PR.

I am not running the full regression test suite because the change is confined to one test.

@SamuelTrahanNOAA Thanks for the quick responses!
I was comparing your template with a global workflow run and would like to ensure that we don't bring any unnecessary HAFS settings into the global nest runs. Do you want me to continue and go through all the namelist parameters in the template?

Yes.

@jkbk2004 - When could this PR be merged?
It is holding up a global-workflow pull request, so I'd rather not delay too long.
The changes are low-risk (no subcomponent PRs) and confined to one regression test. You may be able to combine it with other PRs.

@SamuelTrahanNOAA Sorry for the backlog! We will check if we can combine either #2279 or #2186. Possibly to schedule either tomorrow or Monday.

merged with #2186
