Brief communication: Impact of common ice mask in surface mass balance estimates over the Antarctic ice sheet
Regional climate models compute ice sheet surface mass balance (SMB) over a mask that defines the area covered by glacier ice, but ice masks have not been harmonised between models. Intercomparison studies of modelled SMB therefore use a common ice mask. The SMB in areas outside the common ice mask,...
