The 4th column in the above gives the number of points on the atmosphere grid, which are fractional ocean points (as determined by the aave map), but will receive no data from the ocean->atmosphere map. Maps with such points are unusable in E3SM at as ocn->atm statemaps, because the atmosphere will be expecting ocean data at these points but instead will receive 0. As one of the main state variables it Temperature, this will cause the model to crash with unphysically cold temperatures, or create speckling patterns of stationary low surface temperature ( i.e.: /wiki/spaces/NGDNA/pages/3597565953 ).
