The MEaSUREs Annual Antarctic Ice Velocity Maps, Version 1 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated. New data has been added, extending the temporal coverage to June 30, 2025.
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of annual (1 July to 30 June), 1 km resolution maps of ice component velocities for the Antarctic ice sheet. Data are provided for the year 2000-2001 and for each year from 2005 to 2025. Velocities are derived by applying interferometric analysis techniques to synthetic aperture radar (SAR) data acquired by various satellites and sensors and by feature tracking of optical imagery acquired by Landsat-8.
