MEaSUREs Greenland Monthly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains monthly ice velocity mosaics for the Greenland Ice Sheet derived from Synthetic Aperture Radar (SAR) data obtained by the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX), the European Space Agency's (ESA) Copernicus Sentinel-1A and -1B satellites, and from US Geological Survey (USGS) Landsat 8 optical imagery.

See Greenland Ice Mapping Project (GIMP) for related data.
