$atmgrid = SE Atmosphere grid in Exodus format. These are .g files.
$atmw = SE Atmosphere grid weights. These are _latlon.nc files
$ocngrid = FV MPAS grid file in "scrip" format. These are .scrip.nc files

./GenerateCSMesh --alt --res 30 --file NE30.g # the standard atmosphere SE grid, using the np4" GLL spectral element
./GenerateVolumetricMesh --in NE30.g --np 2 --out NE30pg2.g # An atmosphere "FV" grid (for the new pg2 option where physics is on a FV grid)
Note 12: It is important to use the "–alt" option with older versions of TR, so the mesh ordering matches what is used internally by E3SM. This option was made the default in 2020/2.
Note 23: For SE atmosphere grids, the Exodus file is what is used by the model, and it contains the corners of all the spectral elements. The dual grid (SCRIP format) metadata files are not needed by TempestRemap.
