   Description: 
      Abstract:
         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.
