The maps are derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by the Canadian Space Agency's (CSA) RADARSAT-1, the Japan Aerospace Exploration Agency's (JAXA) Advanced Land Observation Satellite (ALOS), and the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX) satellites, as well as from the European Space Agency's (ESA) C-band Synthetic Aperture Radar data from Copernicus Sentinel-1A and -1B.

In addition, the following measures were performed:
<ul>
<li>Added new map for 2009/2010.</li>
<li>Added ALOS fine-beam data to improve coverage in 2006/2007, 2007/2008, and 2008/2009.</li>
<li>Corrected a substantial error on Rink glacier where the time interval was off by a factor of 2.</li>
<li>Improved baseline fits for consistency in the interior of the ice sheet.</li>
<li>Updated error estimates to better represent the average behavior of the data.</li>
<li>Added/updated shapefiles of satellite tracks for 2014 to 2018 winters.</li>
<li>Added browse files for 2014 to 2018 winters.</li>
<li>Updated the velocity magnitude (vv) file name.</li>
<li>Changed the missing data value for the velocity magnitude (vv) files to -1 and set it as the attribute in all files.</li>
</ul>NSIDCMinor Version2.1<ul>
<li>Published 2017/2018 data.</li>
<li>Updated/replaced shapefiles for winter 2014-2018 products (corrected the shapefile dates).</li>
<li>Changed the magnitude file name from greenland_vel_mosaic[RRR]_[yyyy_yyyy]_vel_v2.ext to greenland_vel_mosaic[RRR]_[yyyy_yyyy]_vv_v2.ext.</li>
<li>Changed the missing data value for the velocity magnitude (vv) files to -1 and set it as the attribute in all files.</li>
