[en] We will present here the first results of the SMB Model intercomparison (SMBMIP) over the Greenland Ice sheet. For the first time, all the modeled SMB estimations over the current climate (1980-2016) will be compared at the pixel scale, on the same grid (1km), on the common ice sheet mask, at the monthly timescale and by using the same forcing (ERA-Interim). The SMB components from RCMs, GCMs and PDD models will be compared with ice core measurements, the SMB data base from Machguth et al. (2016) as well as passive microwave satellite derived melt extent, in the aim of identifying poorly documented areas where model results diverge and where additional measurement campaigns will be needed.
