Hall, DK, Williams, RS, Casey, KA, DiGirolamo, NE, Wan, Z (2006). "Satellite-derived, melt-season surface temperature of the Greenland Ice Sheet (2000-2005) and its relationship to mass balance". GEOPHYSICAL RESEARCH LETTERS, 33(11), L11501.

Abstract
Mean, clear-sky surface temperature of the Greenland Ice Sheet was measured for each melt season from 2000 to 2005 using Moderate-Resolution Imaging Spectroradiometer (MODIS)-derived land-surface temperature (LST) data-product maps. During the period of most-active melt, the mean, clear-sky surface temperature of the ice sheet was highest in 2002 ( - 8.29 +/- 5.29 degrees C) and 2005 ( - 8.29 +/- 5.43 degrees C), compared to a 6-year mean of - 9.04 +/- 5.59 degrees C, in agreement with recent work by other investigators showing unusually extensive melt in 2002 and 2005. Surface-temperature variability shows a correspondence with the dry-snow facies of the ice sheet; a reduction in area of the dry-snow facies would indicate a more-negative mass balance. Surface-temperature variability generally increased during the study period and is most pronounced in the 2005 melt season; this is consistent with surface instability caused by air-temperature fluctuations.
