MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, Version 1

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides velocity estimates determined from Interferometric Synthetic Aperture Radar (InSAR) data for major glacier outlet areas in Greenland, some of which have shown profound velocity changes over the MEaSUREs observation period. The InSAR Selected Glacier Site Velocity Maps are produced from image pairs measured by the German Aerospace Center's (DLR) twin satellites TerraSAR-X / TanDEM-X (TSX / TDX). The measurements in this data set are provided in addition to the ice sheet-wide data from the related data set, MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data.

See Greenland Ice Mapping Project (GIMP) for more related data.

本数据集隶属于美国国家航空航天局（NASA）地球系统数据记录研究环境应用计划（Making Earth System Data Records for Use in Research Environments，简称MEaSUREs），基于合成孔径雷达干涉测量（Interferometric Synthetic Aperture Radar，InSAR）数据，生成了格陵兰主要冰川出口区域的速度估算值，其中部分区域在MEaSUREs的观测周期内呈现出显著的速度变化。本次合成孔径雷达干涉测量选定冰川区域速度图，由德国航空航天中心（DLR）的双星TerraSAR-X / TanDEM-X（TSX / TDX）采集的图像对生成。本数据集的测量数据为相关数据集——基于合成孔径雷达干涉测量数据的MEaSUREs格陵兰冰盖速度图——所提供的冰盖全域数据的补充内容。如需获取更多相关数据，请参考格陵兰冰盖制图计划（Greenland Ice Mapping Project，简称GIMP）。
