Data Set ID:
NSIDC-0776
Data Set Summary:
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 for major glacier-covered regions, derived from Landsat 4, 5, 7, and 8 imagery. Data are available from 1985 to 2018. Data availability is significantly limited prior to 2013 due to image scarcity and low image quality; however annual coverage is nearly complete for the years following the Landsat 8 launch in 2013.
