Surface mass balance (SMB) of polar ice sheets is a key component in quantifying their contribution to global sea-level rise. Accurate, high-resolution projections of SMB are therefore required to force ISMIP7 ice sheet models. In this study, we present preliminary results from SMBMIP, a comparison of several high-resolution SMB products over the Greenland Ice Sheet within the ISMIP7 framework. These products include, among others, SMB projections from the regional climate model MAR, statistical downscaling of MAR and the Earth System Model CESM2, and machine-learning outputs. For a meaningful comparison, participating projections are based on a same CESM2 historical climate and emission scenario. The aim is to explore uncertainties, performance and efficiency of various modelling approaches.
