   Description: 
      Abstract:
         This data set, part of the NASA Making Earth System Data Records for Use in 
         Research Environments (MEaSUREs) program, provides the first comprehensive, 
         high-resolution, digital mosaics of ice motion in Antarctica assembled from 
         multiple satellite interferometric synthetic-aperture radar data. Data were 
         acquired during the International Polar Year 2007 to 2009. 

         These maps were built from spring 2009 data from the Canadian Space Agency 
         (CSA)'s and MacDonald, Dettwiler and Associates Ltd. (MDA)'s RADARSAT-2, 
         spring 2007-2008-2009 data from European Space Agency (ESA)'s Envisat Advanced 
         Synthetic Aperture Radar (ASAR), and fall 2007-2008 data from the Japan 
         Aerospace Exploration Agency (JAXA)'s Advanced Land Observing Satellite (ALOS) 
         Phased Array type L-band Synthetic Aperture Radar (PALSAR), complemented by 
         patches of CSA's RADARSAT-1 data from fall 2000 and ESA's Earth Remote Sensing 
         Satellites ERS-1 and -2 data from spring 1996. Each radar instrument 
         contributes its unique coverage and performance level. The final mosaics 
         assemble 900 satellite tracks and more than 3,000 orbits of radar data. Data 
         acquisitions between 2006 and 2011 are courtesy of the IPY Space Task Group. 

         Data are available via FTP at 450 m and 900 m spacings, in both binary format 
         (.dat) with an ENVI text header (.txt) and NetCDF.

         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.
