Antarctic 5-km Digital Elevation Model from ERS-1 Altimetry
Entry ID: NSIDC-0076

[ Update this Record ]

Summary
Abstract: This data set provides a digital elevation model (DEM) for Antarctica to 81.5 degrees south latitude, at a resolution of 5 km. Approximately twenty million data points were used to generate this data set. Data points were derived from ERS-1 radar altimetry during the geodetic phase from March 1994 to May 1995. The improved density in coverage and resolution, compared with past satellite altimetry ... View entire text

Quality Various methods were applied to improve the accuracy of elevation estimates over the Antarctic ice sheet, including waveform tracking, slope correction, data filtering (tests for return-echo waveform shape, backscatter coefficient, and retracking correction values for each altimeter height estimate), and removal of anomalous orbits.
