Greenland 5 km DEM, Ice Thickness, and Bedrock Elevation Grids, Version 1

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 data are based on approximately 700,000 data points collected in the 1990s from a University of Kansas airborne Ice Penetrating Radar (IPR). Nearly 30,000 data points were collected in the 1970s from a Technical University of Denmark (TUD) airborne echo sounder.The ice thickness grid was subtracted from the DEM to produce a grid of bedrock elevation values. Data set applications include studies of gravitational driving stress and ice volume (mass balance) of the Greenland Ice Sheet.

This is the most recent version of these data.

FAQ

Is the Greenland Surface DEM provided in an alternative format?
Yes. Attached to this article are the following Greenland Surface DEM data files: A little-endian flat-binary file (bambgrl_dem_5km.img) and its associated ENVI header file (bambgrl_dem_5km.img.hdr). A GeoTIFF file (bambgrl_dem_5km.tif).
