Surface Elevation Change (SEC) of the Antarctic Ice Sheet

The change in surface elevation of the Antarctic grounded ice sheet is measured from all available ESA Radar Altimetry missions (ERS-1, ERS-2, ENVISAT, CryoSat-2, Sentinel-3A, and Sentinel-3B) from 1991 to 2021. We provide netCDF products of gridded surface elevation change at 5km resolution for every 5-year period between 1991 and 2021 (stepped by 1-year), and also for the full period of each altimetry mission.
