MEaSUREs ITS_LIVE Antarctic Grounded Ice Sheet Elevation Change V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Metadata Last Checked: July 17, 2025 | Last Modified: 2025-07-17

This data product contains monthly ice sheet elevation change data for Antarctica derived from five radar altimetry missions (Geosat, ERS-1 and -2, Envisat and CryoSat-2) and two laser altimetry missions (ICESat and ICESat-2). Each time step and grid node includes relative error estimates and a quality flag that can be used to filter the data in space and time. The product is also provided with an estimate of static topography in the form of a digital elevation model (DEM), which was used to estimate monthly ice sheet elevation change. With a temporal coverage of 17 April 1985 to 16 December 2020, this product can be used to determine changes in ice sheet mass balance over time.
