MEaSUREs Greenland Annual Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains annual ice velocity mosaicsfor the Greenland Ice Sheet derived from Synthetic Aperture Radar (SAR) data obtained by the German Space Agency's TerraSAR-X/TanDEM-X (TSX/TDX) and the European Space Agency's Copernicus Sentinel-1A and -1B satellites, and from the US Geological Survey's Landsat 8 optical imagery for years 2015 to 2018.

See Greenland Ice Mapping Project (GrIMP) for related data.

本数据集隶属于美国国家航空航天局（National Aeronautics and Space Administration, NASA）旗下的科研环境用地球系统数据记录制作计划（Making Earth System Data Records for Use in Research Environments, MEaSUREs），包含2015年至2018年格陵兰冰盖的年度冰速镶嵌图。该数据集的数据来源包括：德国航天中心的TerraSAR-X/TanDEM-X（TSX/TDX）合成孔径雷达（Synthetic Aperture Radar, SAR）数据、欧洲空间局（European Space Agency, ESA）哥白尼计划的Sentinel-1A与Sentinel-1B卫星SAR数据，以及美国地质调查局（United States Geological Survey, USGS）的Landsat 8光学影像。
