Overview
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.
This data set was originally titled "MEaSUREs Annual Antarctic Ice Velocity Maps 2005-2017."

This color-coded map shows annual ice velocity, in meters per year, across Antarctica. Highest velocities appear in magenta and red, intermediate velocities appear in blue and green, and lowest velocities appear in yellow and peach. The velocities are plotted over a digital elevation model, shown in grayscale. Credit: NASA MEaSUREs AIV Data: JAXA, ESA, CSA, DLR
