Glacier terminus during the 2020-2021 winter season. === Original Data Source === MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR Mosaics, Version 2 This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides digitized terminus positions for 239 Greenland outlet glaciers during 13 winter seasons. Terminus positions were determined from MEaSUREs mosaics of Sentinel-1 and RADARSAT-1 synthetic aperture radar data, with gaps filled using Landsat-7 and -8 panchromatic imagery.
