Brief communication: CESM2 climate forcing (1950-2014) yields realistic Greenland ice sheet surface mass balance
peer reviewed We present a reconstruction of historical (1950-2014) surface mass balance (SMB) of the Greenland ice sheet (GrIS) using a high-resolution regional climate model (RACMO2; ~11 km) to dynamically downscale the climate of the Community Earth System Model version 2 (CESM2; ~111 km).
