We have looked into this found that halving the smoothing radius from the recommended CAM smoothing radius, does a reasonable job reproducing the MPAS smoothing. Some more details can be found in https://github.com/ESCOMP/CAM/issues/507,
Concur with Adam! Half the smoothing radius compared to current default in CAM seems to match MPAS standalone topography well. Below is example from 60-15km MPAS topography: (left) CESM topo software with half default smoothing radius and (right) standalone MPAS topo.
Example: For one degree we use ncube_sph_smooth_coarse=60 which would be ncube_sph_smooth_coarse=30 to match MPAS standalone smoothing.
An issue to discuss updating the software to match the smoothing of MPAS.
