MEaSUREs Multi-year Reference Velocity Maps of the Antarctic Ice Sheet V001
Listed in NASA Earthdata CMR
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains four, as-complete-as-possible 450 m resolution reference maps of ice component velocities for the Antarctic ice sheet.
Description
Maps are available for 1995 – 2001; 2007 – 2009; 2014 – 2017; and 2020 – 2022. Velocities are derived by applying phase analysis and speckle tracking to satellite synthetic aperture radar data, and by feature tracking of visible imagery obtained by the Operational Land Imager (OLI) on board Landsat-8.
Data also include velocity standard deviation and mean velocity standard error; the number of observation pairs used for each pixel; start and end dates used for each pixel; and a mask that indicates ice front and grounding line locations.
