Greenland 5 km DEM, Ice Thickness, and Bedrock Elevation Grids
Entry ID: NSIDC-0092

[ Update this Record ]

Summary
Abstract: A Digital Elevation Model (DEM), ice thickness grid, and bedrock elevation grid of Greenland acquired as part of the PARCA program are available in ASCII text format at a 5 km grid spacing in a polar stereographic projection. DEM data are a combination of ERS-1 and Geosat satellite radar altimetry data, Airborne Topographic Mapper (ATM) data, and photogrammetric digital height data. Ice thickness ... View entire text

Quality Various methods were applied to improve the accuracy of elevation estimates over the Greenland 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. Errors in the estimate of derived ice thickness measurements ... View entire text
