Grid Stuff (Supergrid, Bathymetry, Vgrid)

Grid Stuff (Supergrid, Bathymetry, Vgrid)#

In CrocoDash, the first step is grid generation. CrocoDash directly wraps, with no modifications, mom6_bathy. Please pursue the mom6_bathy documentation for all questions. There is no extra nuance to using CrocoDash grids, the only thing you need to is import the modules through CrocoDash.

Editing Topography After Case Creation#

If you use the TopoEditor (or otherwise modify the topography file) after creating your CESM case, be aware that:

  • If your edits change the land-sea mask, the ESMF mesh file (used by CESM for domain decomposition and remapping) must be regenerated to match.

  • If you only change depths without changing the mask, regeneration is not necessary.

To regenerate the ESMF mesh from an updated Topo object:

topo.write_esmf_mesh(path_to_esmf_mesh_file)

The path to the ESMF mesh file for your case is stored as case.esmf_mesh_path after case creation, or you can find it in the case’s input directory under ocnice/ESMF_mesh_<gridname>_<id>.nc.
