Seasat and GEOSAT Altimetry for the Antarctic and Greenland Ice Sheets
Entry ID: NSIDC-0053

[ Update this Record ]

Abstract: The Ice Altimetry System (IAS) CD-ROM contains surface elevations of the Antarctic and Greenland ice sheets derived from Seasat and GEOSAT radar altimetry data. The Seasat data were collected for a continuous 90 days in 1978, at latitudes between 72 degrees South and 72 degrees North. GEOSAT was launched in 1985 and placed in a nearly identical orbit to Seasat, also at latitudes of between 72 ... View entire text
