Description:

Updates to the MPAS dynamical core interface to the UFSATM.

New advancements within th UFSATM:

Constituent handling and scalar advection. New module, ufs_mpas_constituents, which contains interface code between MPAS constituents and the UFS.
MPAS native output stream. Contained within the ufs_mpas_io module. This module also includes procedures for reading in the various MPAS input streams (e.g., invariant, input, sfc_input)
Support for lateral boundary condition (LBC) stream. New module with code related to regional MPAS configurations, ufs_mpas_boundaries. The LBCs are updated during forecast integration, _run phase in ufs_mpas_subdriver.F90.
Progress on CCPP physics coupling. New MPAS input stream (sfc_input) for gridded fields needed by the physics. Additional P2D coupling procedures to handle the state evolution between physics group and dycore calls. Added diagnostics to output stream.

Within the UWM, the changes are entirely to the MPAS testing configurations within the UWM.

@dustinswales Baseline creation ran successfully on Hercules, but on Derecho, I am seeing errors that are causing the baseline creation to fail. Errors are similar for both tests, so here's what I see for control_gfs_mpas_gnu:

Hmmm. That's odd.
@scrasmussen Do you have any ideas/insight on this?

gspetro-NOAA · 2026-04-28T15:57:54Z

@dustinswales Any update on the Derecho troubleshooting? (Not sure if anything is happening offline.) If you don't think this problem can be solved today, we can remove derecho from the machine list, file an issue, and you can put in a fix with the next PR (or issue a bugfix PR).

@gspetro-NOAA I just figured out the issue on Derecho. The default PIO output type is PNETCDF, which doesn't work on Derecho. If I change the default PIO output type to NETCDF it runs on Derecho.

I agree with your suggestion. (Remove Derecho, open issue, and I'll add to #3201)

For references, here are the changes causing trouble in the UFSATM NUOPC Cap:

-       cvalue = 'NETCDF'
-       pio_iotype = PIO_IOTYPE_NETCDF
+       cvalue = 'PNETCDF'
+       pio_iotype = PIO_IOTYPE_PNETCDF
