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 and -1B imaging satellites starting in January 2015.

See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GIMP)</a> for related data.

Version Description

Changes to this version include: - Data were reprocessed with upgraded software and a revised DEM - The spatial resolution of the uncalibrated product was improved from 50 to 25 meters - Two new parameters: (1) a calibrated sigma0 radar backscatter product with a 50 m spatial resolution; and (2) a calibrated and radiometrically terrain-corrected gamma0 radar backscatter product, also at 50 m resolution - The products have been simplified, with the mosaics merged into a single cloud-optimized GeoTIFF and thus replacing the multiple .tif, .vrt, and .ovr files included in Version 2. - The temporal coverage was expanded
