Basal Melt (ESA POLAR+ 4D Greenland Experimental Dataset)
Monthly basal melt discharge (2001-2019) at the five selected drainage basins on the Greenland ice sheet; NEGIS, Northern Lakes, Southern Lakes, Store, and Watson. This is based on solid and liquid discharge estimates for each marine-terminating glacier, thus assessing the seasonal and annual export of freshwater from the land ice to the fjords. For each study site, a *.csv is available containing the total (sum of the components due to geothermal heating, frictional heating and surface water heating) monthly basal discharge rates.
