MEaSUREs Greenland Annual Ice Sheet Velocity Mosaics from SAR and Landsat V005

공공데이터포털

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains annual ice velocity mosaics for the Greenland Ice Sheet. Velocities are derived from synthetic aperture radar (SAR) data, obtained by TerraSAR-X/TanDEM-X and Sentinel-1A and -1B, and from optical imagery acquired by Landsat 8 and Landsat 9. See Greenland Ice Mapping Project (GrIMP) for related data.

공공데이터포털

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. The maps are derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by the Canadian Space Agency's (CSA) RADARSAT-1, the Japan Aerospace Exploration Agency's (JAXA) Advanced Land Observation Satellite (ALOS), and the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX) satellites, as well as from the European Space Agency's (ESA) C-band Synthetic Aperture Radar data from Copernicus Sentinel-1A and -1B. See Greenland Ice Mapping Project (GIMP) for related data.

MEaSUREs MODIS Mosaic of Antarctica 2013-2014 (MOA2014) Image Map, Version 1

공공데이터포털

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, includes two image maps - a snow grain size map and a surface morphology map - provided at two different resolutions of 125 m and 750 m. The maps were produced from composited image swath data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) over Antarctica for the 2013-2014 austral summer season.

MEaSUREs Greenland 6 and 12 day Ice Sheet Velocity Mosaics from SAR V001

공공데이터포털

This data set contains 6 and 12 day surface velocity estimates for the Greenland Ice Sheet and periphery derived from images acquired between 2015–2021 by the European Space Agency (ESA) Copernicus Sentinel-1A and Sentinel-1B satellites.

MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR Mosaics V002

공공데이터포털

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of annual, digitized (polyline) ice front positions for 239 outlet glaciers in Greenland. Ice front positions are derived from Sentinel-1A, Sentinel-1B, and RADARSAT-1 synthetic aperture radar (SAR) mosaics, plus imagery from Landsat 1 through Landsat 5 and Landsat 7 and Landsat 8. Although temporal coverage varies by glacier, data are available for the winter seasons 1972–1973 through 2020–2021. Data are provided as shapefiles. See Greenland Ice Mapping Project (GrIMP) for related data.

MEaSUREs InSAR-Based Antarctica Ice Velocity Map V002

공공데이터포털

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides the first comprehensive, high-resolution, digital mosaics of ice motion in Antarctica assembled from multiple satellite interferometric, synthetic-aperture radar systems. Data were largely acquired during the International Polar Years 2007 to 2009, as well as between 2013 and 2016. Additional data acquired between 1996 and 2016 were used as needed to maximize coverage. See Antarctic Ice Sheet Velocity and Mapping Data for related data.
