MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data  View Catalog Page Entry ID
NSIDC-0478
Summary
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides annual ice-sheet-wide velocity maps for Greenland, derived using Interferometric Synthetic Aperture Radar (InSAR) data from the RADARSAT-1 satellite. The data set currently contains ice velocity data for the winter of 2000-2001 and 2005-2006, 2006-2007, and 2007-2008 acquired from RADARSAT-1 InSAR data from the Alaska Satellite Facility (ASF), and a 2008-2009 mosaic derived from the Advanced Land Observation Satelitte (ALOS) and TerraSAR-X data.
Data are available via FTP, in 4-byte big-endian Institute of Electrical and Electronics Engineers (IEEE) floating point and GeoTIFF (.tif) formats.
Note. These data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed from this documentation.
