Evaluation of reconstructions of snow/ice melt in Greenland by regional atmospheric climate models using laser altimetry data
peer reviewed he surface mass balance (SMB) of the Greenland Ice Sheet critically depend on the intensity of ice/snow melt in its ablation zone, but in‐situ data have been too limited to quantify the error of regional climate models. Here, we use 23 years of NASA satellite and airborne laser altimet...
