A NEW BEDROCK AND SURFACE ELEVATION DATA SET FOR MODELLING THE
A new digital elevation model of the surface of the Greenland ice sheet and surrounding rock outcrops has been produced from a comprehensive suite of satellite and airborne remote sensing and cartographic data sets. The surface model has been regridded to a resolution of 5 km, and combined with a ne...
