NSIDC is pleased to announce the release of two Antarctic data sets, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program. The MEaSUREs program aims to develop consistent global and continent scale data records related to earth science, or Earth System Data Records (ESDRs).
- MEaSUREs InSAR-Based Antarctica Velocity Map (nsidc-0484) provides the first comprehensive, high-resolution, digital mosaic of ice motion in Antarctica. The data set was assembled from multiple satellite interferometric synthetic-aperture radar data, acquired during the International Polar Year 2007 to 2009.
- MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry (nsidc-0498) provides a high-resolution map of grounding lines in Antarctica, derived using 17 years of differential satellite synthetic aperture.
