Description

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains 6 and 12 day surface velocity estimates for the Greenland Ice Sheet and periphery. Velocities are derived from images acquired by the European Space Agency (ESA) Copernicus Sentinel-1A and Sentinel-1B satellites.

See <a href="http://nsidc.org/grimp">Greenland Ice Mapping Project (GrIMP)</a> for related data sets.

Version Description

Changes for the version include: - Temporal coverage extended - Data recalibrated relative to previous versions to reduces biases imposed by quadratic fits to control points - Correction added for the submergence/emergence velocity - Addition of interferometric phase data where available
