Stitched radar image maps of Greenland (Sentinel-1A/1B)
What it measures. Seamless, stitched-together radar image maps (mosaics) of Greenland's coastline and the edge of its ice sheet, available as 6-day and 12-day composites at 50-meter detail.
How it's made. Assembled from C-band radar collected by Europe's Sentinel-1A, -1B, and -1C satellites, which can image through clouds and darkness.
How & where you'd use it. Supports monitoring of Greenland's ice sheet and glaciers, part of the broader Greenland Ice Mapping Project; a ready-to-view radar basemap for ice studies.

Official description
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of 6-day and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery. The mosaics are derived from C-band Synthetic Aperture Radar (C-SAR) acquired by the Copernicus Sentinel-1A, -1B, and -1C satellites. See <a href="http://nsidc.org/grimp">Greenland Ice Mapping Project (GrIMP)</a> for related data sets.
