Description

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

Version Description

The following represent key updates as of Version 2. For a detailed list of the differences between versions 1 and 2, refer to the User Guide. Data set temporal resolution now runs through 30 November 2019. Application of a new DEM: NSIDC-0715 Addition of dT GeoTIFFs, a temporal offset parameter. Removal of bad data and addition of overlooked data. As a result, mosaics show more areas with no data, the min/max ex and ey values are lower and feature counts differ. Cloud-optimized GeoTIFFs along with auxiliary files now available
