Generate a grid specification data file for ocean.
1. "hgrid": only horizontal grid will be created.
2. "vgrid": only vertical grid will be created
4. "hgrid_topog" : horizontal grid, topography and land/sea mask will be created.
Topography is obtained by remapping onto current grid from some topography source data.
land/sea mask is determined by the topography. In this case, topography does not depend
on vertical grid and no vertical grid will be created. You need to set topog_depend_on_vgrid of
topog_nml to .false. .
5. "hgrid_vgrid_topog": horizontal grid, vertical grid, topography and land/sea mask
will be created. The topography is mom4-specific topography (could be idealized or from
some source file), which depends on vertical grid. The land/sea mask is determined by
topography. In this case, you need to set topog_depend_on_vgrid of topog_nml to .true. .
