Geothermal heat flux distribution for the Greenland ice sheet, derived by combining a global representation and information from deep ice cores

Distribution of the geothermal heat flux under the Greenland ice sheet, derived by combining the global heat-flow representation by Pollack and others (1993, Rev. Geophys. 31, doi: 10.1029/93RG01249) and point information at five deep ice-core locations (GRIP, Dye 3, Camp Century, NGRIP, NEEM). Update of two earlier versions by Greve (2005, Ann. Glaciol. 42, doi: 10.3189/172756405781812510) and Greve and Herzfeld (2013, Ann. Glaciol. 54, doi: 10.3189/2013AoG63A085). Gridded NetCDF files are available for two different grids (EPSG:3413 grid: polar stereographic projection, standard parallel 70N, central meridian 45W; Bamber grid: polar stereographic projection, standard parallel 71N, central meridian 39W) and three different resolutions (5 km, 10 km, 20 km).
