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（NASA）的地球系统数据记录研发以服务科研环境（Making Earth System Data Records for Use in Research Environments，缩写MEaSUREs）计划，包含基于多源遥感数据生成的格陵兰冰盖年度冰速镶嵌图：数据来源包括德国航空航天中心的TerraSAR-X/TanDEM-X（TSX/TDX）卫星与欧洲空间局哥白尼计划的Sentinel-1A、Sentinel-1B卫星获取的合成孔径雷达（Synthetic Aperture Radar，缩写SAR）数据，以及2015至2018年美国地质调查局的Landsat 8光学影像。相关数据可参阅格陵兰冰盖制图项目（Greenland Ice Mapping Project，缩写GrIMP）。
