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.

MEaSUREs Updates Antarctic Grounding Line from Differential Satellite Radar Interferometry Data Set

25 October 2016

Version 2 of Antarctic Grounding Line from Differential Satellite Radar Interferometry data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides 22 years of comprehensive high-resolution mapping of grounding lines in Antarctica, derived using differential satellite synthetic aperture radar interferometry (DInSAR) data.

MEaSUREs Releases Multi-year Greenland Ice Sheet Velocity Mosaic

30 August 2016

The Multi-year Greenland Ice Sheet Velocity Mosaic data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains a multi-year ice-sheet-wide velocity mosaic for Greenland derived from Interferometric Synthetic Aperture Radar (InSAR), Synthetic Aperture Radar (SAR), and Landsat 8 optical imagery data.

New Data added to MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR

4 March 2016

The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR data set at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been updated with velocity maps for 2013 and 2014. In addition, this update replaces all data for the Jakobshavn Isbrae, Helheim, and Kangerdlugssuaq glaciers with new maps that offer improved temporal sampling and address previous artifacts related to slope discontinuities at these glaciers’ terminii.

These data are generated through a grant from the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
