MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data, Version 1

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 derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by RADARSAT-1, the Advanced Land Observation Satellite (ALOS), and the TerraSAR-X satellite.本数据集隶属于美国国家航空航天局（NASA）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），包含基于RADARSAT-1、先进陆地观测卫星（Advanced Land Observation Satellite, ALOS）以及TerraSAR-X卫星获取的干涉合成孔径雷达（Interferometric Synthetic Aperture Radar, InSAR）数据所生成的格陵兰岛冰盖全域季节性（冬季）速度分布图。
