@chan-hoo I'm currently working on running the aqm_grid_AQM_NA13km_suite_GFS_v16 WE2E test on Hera. Once it successfully completes, I will move forward with approving this PR.

I do have a question about the closing of issue #684. Should we keep this issue open until all machines have AQM-specific tasks like WCOSS2, Cheyenne, and Hera and all use miniconda_regional_workflow_cmaq? It seems like this would need to be down before closing the issue. If you are okay with it, I would like to remove this issue from the issues that can be closed with this PR. Thanks!

@MichaelLueken, I agree with you. Since AQM is not available on other machines, you can close the issue once this PR is merged.

@chan-hoo Since AQM can only run on Cheyenne, Hera, and WCOSS2, I will go ahead and keep the issue set as closable when this PR is merged.

@chan-hoo , @MichaelLueken - is it only the issue with staged data for running the AQM on other machines?.. I'm still working on moving the AQM data to the rest of the systems, so it should not be an issue when finished.

@natalie-perlin, you don't have to hurry. Besides, AQM is not available on other machines yet.

@MichaelLueken, updated!

@chan-hoo - what is needed to make AQM available on all the machines?
Is it only miniconda_regional_workflow_cmaq environment and data staged?

@natalie-perlin, I think so. The AQM input data are necessary and their paths should be defined in ush/machine/[machine].yaml. In addition, the module files in modulefiles/tasks/[machine]/[task] should be updated.

@chan-hoo - then it would be quite simple to update to the rest of the platforms! I already transferred data to most of the platforms, in ./UFS-SRW_data/aqm_data/ and
./UFS_SRW_data/develop/aqm_data/ and ./UFS_SRW_data/develop/input_model_data/FV3GFS (if this all that needed), and to install miniconda3 env on the platforms that may be missing it.

Note about Orion:
I'm preparing hpc-stacks in a new dedicated space, installing miniconda3, for both Orion and Hercules, as well as moving all the UFS_SRW_data to a new location that is accessible with epic role account:
/work/noaa/epic/role-epic .

@natalie-perlin, the issue is that the input data of NEXUS and point source is huge (NEXUS > 100TB, point source > 100GB). You can check their size on Hera (/scratch2/NCEPDEV/naqfc/RRFS_CMAQ/emissions/nexus). I don't think AQM will need the entire directory of NEXUS, but you'll need help from ARL.

@chan-hoo -
Yes, we probably won't need too much data to keep under epic account on all the machines. I just wonder if the subsets that you provided could be good enough to have AQM running, with the option not to use /scratch2/NCEPDEV/naqfc/RRFS_CMAQ/emissions/nexus data if certain directories are not set or found...
What is ARL?..

NOAA's Air Resources Laboratory. They maintain the nexus and point source directories.

@natalie-perlin @chan-hoo We have actually been trying to get the system up and running and most of the input data is probably already transferred for the GEFS/ UFS-Aerosol work in the fix directory. But we also maintained a backup on the each system for development work. We have the emissions here on Orion: /work2/noaa/naqfc/bbaker/emissions/nexus

@bbakernoaa - thank you for the info!

@bbakernoaa @chan-hoo
Are all the data under /work2/noaa/naqfc/bbaker/emissions/nexus/ on Orion, or is there another location for fixed files for GEFS/ UFS-Aerosol work?

Is it correct that we do have all the data on Hera and Orion for running AQM? Cheyenne and other systems have [partial] data from Chan-Hoo in EPIC-maintained space in .../UFS_SRW/data/..., but we may need other (nexus) as well.

The coverage WE2E tests were manually ran on Orion and all successfully passed:

Awaiting successful completion of the rest of the automated tests before merging this work to develop.

The automated Jenkins tests have successfully passed on Cheyenne, Hera, and Jet. With the success of the manual run on Orion, all tests have successfully passed. Given this and the two approvals for this work, I will now move forward with merging this work to develop.
