MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B, Version 3
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 Greenland Ice Mapping Project (GIMP) for related data.
This is the most recent version of these data.
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
