General instructions for creating new grids are at Running E3SM on New Atmosphere Grids , which also include specific instructions for RRM.
Atmosphere grids have a grid quality metric which measure the element distortion (see Running E3SM on New Atmosphere Grids). A high quality RRM grid with smooth transition region will have a value <= 4.
