Abstract
Radar altimeter measurements from the Geos 3 satellite are being utilized to define the topography of the southern Greenland ice sheet between latitudes 60°N and 65°N. The resultant elevations have been correlated with two geoceiver sites on the ice surface; the agreement is within a few meters. The internal repeatability of the altimeter‐derived elevations has been assessed at the crossovers of the satellite ground tracks; the observed agreements varied from 0.07 to 3.10 m, intervening times being 1 day and 674 days, respectively. Improved knowledge of the temporal changes in the topographic expression of the continental ice sheets, via satellite altimetry, will significantly add to the understanding of glaciological and climatological processes.Keywords
