MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry, Version 2 (NSIDC-0498)
This is the most recent version of these data.
In Version 2, the temporal coverage now includes 22 years from 1992 to 2014. In addition, the data format changed to shapefiles.
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides 22 years of comprehensive high-resolution mapping of grounding lines in Antarctica from 1992 to 2014. The data were derived using differential satellite synthetic aperture radar interferometry (DInSAR) measurements from the following platforms: Earth Remote Sensing Satellites 1 and 2 (ERS-1 and ERS-2), RADARSAT-1, RADARSAT-2, the Advanced Land Observing System Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR), Cosmo Skymed, and Copernicus Sentinel-1. See Antarctic Ice Sheet Velocity and Mapping Data for related data.
