Geothermal heat flux interpolated from ice core measurements in
miliwatts per square meter.

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

The data present a distribution of the geothermal heat flux (GHF)
for Greenland, which is an update of two earlier versions by Greve
(2005, Ann. Glaciol. 42) and Greve and Herzfeld (2013, Ann. Glaciol.
54). The GHF distribution is constructed in two steps. First, the
global representation by Pollack et al. (1993, Rev. Geophys. 31) is
scaled for the area of Greenland. Second, by means of a
paleoclimatic simulation carried out with the ice sheet model
SICOPOLIS, the GHF values for five deep ice core locations are
modified such that observed and simulated basal temperatures match
closely. The resulting GHF distribution generally features low
values in the south and the north-west, whereas elevated values
prevail in central North Greenland and towards the north-east. The
original source data are provided as NetCDF files on two different
grids (EPSG:3413 grid, Bamber grid) that have frequently been used
in modelling studies of the Greenland ice sheet, and for the three
different resolutions of 5 km, 10 km and 20 km.
