MEaSUREs Multi-year Reference Velocity Maps of the Antarctic Ice Sheet, Version 1

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of three as-complete-as-possible mosaic maps of velocities on the Antarctic ice sheet for the time periods 1995–2001, 2007–2009, and 2014–2017. The maps are posted at 450 m in the WGS 84/Antarctic Polar Stereographic projection.

In addition to ice velocity, the data set provides maps of velocity error and standard deviation, counts of velocity estimates used per pixel, date ranges, and masks that delineate the ice fronts and grounding lines for the each period.
