MEaSUREs Greenland Quarterly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 3

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains quarterly (three-month interval) ice velocity mosaics for the Greenland Ice Sheet. This product is derived from Synthetic Aperture Radar (SAR) data obtained by the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX), by the European Space Agency's (ESA) Copernicus Sentinel-1A and -1B satellites, and from the US Geological Survey's (USGS) Landsat 8 optical imagery.

See Greenland Ice Mapping Project (GIMP) 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）用于研究环境的地球系统数据记录制作（Making Earth System Data Records for Use in Research Environments, MEaSUREs）计划，包含格陵兰冰原的季度（每三个月为间隔）冰速镶嵌图。该产品的数据来源包括德国航空航天中心（German Aerospace Center, DLR）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）哥白尼计划旗下的哨兵-1A与哨兵-1B卫星SAR数据，以及美国地质调查局（US Geological Survey, USGS）的Landsat 8光学影像数据。相关数据可参考格陵兰冰制图项目（Greenland Ice Mapping Project, GIMP）。
