As noted in https://github.com/hrsdawson/ACCESS-WOMBAT_01deg_BGC_validation/issues/3#issuecomment-1341898663, the diagnostic `npp3d` is calculated incorrectly (it's phytoplankton growth (f11) minus grazing (f21), but should be phytoplankton growth minus linear mortality (f22)). https://github.com/mom-ocean/MOM5/blob/5126b546f1e386b6d6dcf8a62e23af692055aa92/src/mom5/ocean_csiro_bgc/bio_v3.inc#L347-L348 We could fix...

Hello, I downloaded the MOM5 code to the WHOI supercomputer. After compiling GFDL-ESM2M, I tried to run it. Unfortunately, I quickly ran into segmentation faults when running it. I attached...

Many grid variables (`area_t`, `area_u`, `geolon_t`, `geolat_t`, etc) are saved with no mask, but others including `dxt`, `dyt`, `dxu`, `dyu` are land-masked - e.g. see `/g/data/ik11/grids/ocean_grid_10.nc`. This makes it impossible...

Despite the CI [running without error](https://github.com/mom-ocean/MOM5/actions/runs/3034198754/jobs/4883040710) it seems the CMake build isn't correctly setting the C compiler flags so the C netCDF headers are used.

The `gregorian` calendar option for MOM5 implements a [`proleptic_gregorian` calendar](https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar) https://github.com/mom-ocean/MOM5/blob/baaf7ed1baf4543bc821d97402a94792b4044ac4/src/shared/time_manager/time_manager.F90#L2799-L2807 whereas the CF conventions state that a `gregorian` calendar attribute is mixed Julian/Gregorian, and a proleptic Gregorian must have...

Dear All, the MOM5 Google group seems to be down (perhaps because of all the recent spam messages?). I will place my question here if you don't mind. I am...

It seems that the diagnostics from the [gyre_overturn_diagnose](https://github.com/mom-ocean/MOM5/blob/59e0aad14896027d4c11a936b936a0325e77dbcf/src/mom5/ocean_tracers/ocean_tracer_advect.F90#L7227-L7412) routine cannot be the _only_ diagnostic(s) in an output file. Doing so results in those diagnostics silently being incorrect. Adding any additional...

See #389 for context and details. Reiterating from that issue: These changes should not alter the current behaviour of MOM5 if the `generic_tracer` code in the local `ocean_shared` directory is...

We've recently [suggested changes to NOAA-GFDL/ocean_BGC `generic_tracers`](https://github.com/NOAA-GFDL/ocean_BGC/pull/35) to provide a way to pass the salt restoring/correction applied by the ocean model to generic tracers. Those proposed changes add a new...
