MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data, Version 2

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains seasonal (winter) ice-sheet-wide velocity maps for Greenland derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by RADARSAT-1, the Advanced Land Observation Satellite (ALOS), and the TerraSAR-X satellite.

Note: These data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed.

Version Summary:

For Version 2, all velocity maps underwent additional screening for quality control and bad data points were removed. In addition:

  • Improved baseline fits enhance consistency in the interior;
  • Updated error estimates better represent the average behavior of the data;
  • ALOS fine-beam data have been added to improve coverage;
  • A new velocity map is included for 2009/2010
