Abstract
[1] Degree‐day factors (DDFs) are calculated for the ice
sheet ablation zone in southwest Greenland, using measurements
of automatic weather stations and a regional atmospheric
climate model. The rapid increase of DDFs for
snow and ice towards higher elevations is caused by the
increasing dominance of short daytime melting and nocturnal
refreezing. This spatial inhomogeneity can be avoided
by choosing a lower threshold for daily average 2 m air temperature
(268 K instead of 273.15 K) for the degree‐day calculation.
