MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR V004
Listed in NASA Earthdata CMR
Description
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides velocity estimates determined from Interferometric Synthetic Aperture Radar (InSAR) data for major glacier outlet areas in Greenland, some of which have shown profound velocity changes over the MEaSUREs observation period. The InSAR Selected Glacier Site Velocity Maps are produced from image pairs measured by the German Aerospace Center's (DLR) twin satellites TerraSAR-X / TanDEM-X (TSX / TDX).
The measurements in this data set are provided in addition to the ice sheet-wide data from the related data set, <a href="nsidc.org/data/nsidc-0478">MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data</a>. See <a href="nsidc.org/grimp">Greenland Ice Mapping Project (GrIMP)</a> for more related data.
