Overview

This data set from the Inter-Mission Time Series of Land Ice Velocity and Elevation (ITS_LIVE) project, part of NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of regionally compiled, mean annual surface velocities, plus climatological means, for major glacier-covered regions. Velocities are derived from imagery acquired by the Sentinel-1 and Sentinel-2 and Landsat 4, 5, 7, 8, and 9 satellites. Data are available from 1985 to 2022, with nearly complete annual coverage provided after 2013.
