Description of changes

A companion to ESMCI/ccs_config_cesm#255, this PR is necessary to support a new runoff data set

Specific notes

Contributors other than yourself, if any: @manishvenu

CDEPS Issues Fixed (include github issue #): N/A

Are there dependencies on other component PRs (if so list): CESM will also need ESMCI/ccs_config_cesm#255

Are changes expected to change answers (bfb, different to roundoff, more substantial): this should be bfb in all tested configurations; we are adding a new data stream, but not altering any existing ones.

Any User Interface Changes (namelist or namelist defaults changes): No

Testing performed (e.g. aux_cdeps, CESM prealpha, etc): This will be thoroughly tested before being taken out of draft mode

Hashes used for testing:

@mnlevy1981 Hi Mike - what is the status of this PR?

[mnlevy1981]

I definitely need to move some files around for the companion PR in ccs_config_cesm; I'll do that today and also check in with @manishvenu to see if any of the data sets have changed or if this is ready to go. Thanks for the reminder, this had fallen off my radar.

@manishvenu this should come out of draft and be marked ready for review, right? Or does ESMCI/ccs_config_cesm#255 need to be finished first?

Hey @mnlevy1981, I think this one can be done first? I'm not an expert on what order it needs to come in, but this one seems right.

I think it's ready for review, but will post a new GLOFAS path tomorrow.

Hey @mnlevy1981,

I moved the GLOFAS files to a similar place to the JRA runoff files, here is the new paths and command:

Files: $DIN_LOC_ROOT/ocn/glofas/v4/GLOFAS.v4.dis24.%y.nc
MeshFIle: $DIN_LOC_ROOT/ocn/glofas/v4/metadata/GLOFAS.v4.ESMFmesh.nc

The one question I had is that all the runoff meshfiles are in dlnd. Do we want to move GLOFAS meshfile there?

Thanks,
Manish V.

Yeah, I think we want it to be named lnd/dlnd7/GLOFAS/GLOFAS.v4.dis24.ESMFmesh_20260501.nc (and we need to drop the NaN _FillValue attributes)

Hey @mnlevy1981,

I don't have permissions to add the ESMF Mesh here. I've generated the mesh here: /glade/campaign/cesm/cesmdata/cseg/inputdata/ocn/glofas/v4/metadata/GLOFAS.v4.dis24.ESMFmesh_20260501.nc

I just copied it to the correct directory, and we can run rimport next week after testing everything in a fresh sandbox
