Version 2 of MEaSUREs ITS_LIVE Regional Glacier and Ice Sheet Surface Velocities is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This new version contains mean annual surface velocities (1984–2022), plus climatological mean velocities (2014–2022), for 16 glacier-covered regions. Velocities are derived by applying the autonomous Repeat Image Feature Tracking (autoRIFT) processing chain to imagery acquired by the Sentinel-1, Sentinel-2, and Landsat 4, 5, 7, 8, and 9 satellites, and data are provided on 120 m resolution grids. This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
Version 1 of this data set will be retired from the NSIDC DAAC on 26 August 2025. Upon retirement, data will no longer be accessible, but all related documentation will remain available on the data set web page for future reference.
