MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data
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: Although this data set has been screened for anomalously large errors, at this stage they are Version 1 products and some significant errors may persist (>20 m/yr). In addition, these data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed.
