A new ice thickness and bed data set for the Greenland ice sheet 2: Relationship between dynamics and basal topography. Journal of Geophysical Research. 106(D24): 33781-33788. Data provided by the National Snow and Ice Data Center DAAC, University of Colorado, Boulder, CO, USA. Available at http://nsidc.org/data/nsidc-0092.html. 25 October 2006. Background: Digital Elevation Model (DEM) data are a combination of European Remote-Sensing (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. Bamber subtracted the ice thickness grid from the DEM to produce a grid of bedrock elevation values. Bamber, J.L., R.L. Layberry, S.P. Gogenini. 2001.
