Does ROMS need the atmospheric forcing files in this format? Or could we also write the forcing data into a zarr store? Probably not since the model only knows how to read netcdf files?
Correct, ROMS only knows how to read NetCDF. The files don't necessarily have to be sorted by months, though -- we could make new files as frequently or as infrequently as we want.
The matlab scripts produce atmospheric forcing files sorted by months, e.g.,
