Recommended Settings for E3SM
All mappings should be tested as described in the "Testing and Validating Mapping Files" section below. This testing is necessary, but not sufficient to ensure good results.
E3SMv2 with pg2
ATM FV grids with physics on the 2x2 physgrid (i.e. pg2) coupled to FV ocean and FV land. E3SMv2 will still use the spectral element dynamical core on the GLL grid, but the coupling between component always happens between the physics columns, which are now on a FV grid.
