New Version for MEaSUREs InSAR-Based Antarctica Ice Velocity Map

21 April 2017

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has released Version 2 of MEaSUREs InSAR-Based Antarctica Ice Velocity Map. Major updates to the data set include data from 2011-2016 acquired from RADARSAT-2, Sentinel-1, TerraSAR-X, and TanDEM-X. Landsat-8 optical imagery also was integrated into the data to improve coverage. The mosaicking method was updated to make best use of the large number of scenes used for the mosaic. In addition, several new parameters are included for assessing the quality of the data: the standard deviation of vx and vy for each pixel and count of scenes used for each pixel. Coverage increased from 95.1% to 99.6% and a reduction in error was achieved due to the utilization of more data.

This project was funded by the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program.

MEaSUREs Releases New Versions for Three Data Sets

12 April 2017

Three data sets in the NASA’s Making Earth System Data Records for Use in Research Environments (MEaSUREs) program are now available in a new version from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The new version, 1.1, corrects the location of the upper left pixel in each GeoTIFF file. The corrected location of the upper left pixel is the distance in meters from the north pole to the upper left corner of the upper left pixel, effectively shifting the location by one-half pixel to the upper left relative to their positions in the previous version. Only the geolocation metadata in each GeoTIFF has changed; the data array is the same as in the previous version.
