Sample version 2.0 ITS_LIVE Sentinel-1 image pair product of ice velocity in Greenland

21 samples of version 2.0 ITS_LIVE Sentinel-1 image pair product of ice velocity in three test regions of Greenland Ice Sheet Sensor: Sentinel-1A/B Processor: ISCE v2.4.1 (topsApp -> Geogrid v1.4.0 -> autoRIFT v1.4.0) Project: NASA MEaSUREs project ITS_LIVE Region 1 (69.13N, 50.88W; Jakobshavn Isbræ Glacier): 7 ascending image pairs Region 2 (77.61N, 42.79W; central north of interior Greenland): 3 ascending image pairs Region 3 (72.48N, 35.87W; central south of interior Greenland): 10 descending image pairs and 1 ascending image pair This serves as a supplementary dataset for the companion journal article submitted to Earth System Science Data (to appear soon). Acknowledgement: This effort was funded by the NASA MEaSUREs program in contribution to the Inter-mission Time Series of Land Ice Velocity and Elevation (ITS_LIVE) project (https://its-live.jpl.nasa.gov/) and through Alex Gardner’s participation in the NASA NISAR Science Team本数据集包含21份v2.0版本的ITS_LIVE（Inter-mission Time Series of Land Ice Velocity and Elevation）哨兵-1（Sentinel-1）图像对冰速产品，覆盖格陵兰冰盖的三个试验区。传感器为哨兵-1A/B（Sentinel-1A/B），处理流程采用ISCE v2.4.1（topsApp -> Geogrid v1.4.0 -> autoRIFT v1.4.0）。本数据集隶属于美国国家航空航天局（National Aeronautics and Space Administration，NASA）MEaSUREs项目下的ITS_LIVE项目。区域1（69.13°N，50.88°W；雅各布港冰川（Jakobshavn Isbræ Glacier））：包含7幅升轨图像对；区域2（77.61°N，42.79°W；格陵兰内陆北部中部）：包含3幅升轨图像对；区域3（72.48°N，35.87°W；格陵兰内陆南部中部）：包含10幅降轨图像对与1幅升轨图像对。本数据集为投稿至《地球系统科学数据（Earth System Science Data）》的配套期刊论文的补充数据集，即将正式刊出。致谢：本工作由NASA MEaSUREs项目资助，用于支持ITS_LIVE项目（https://its-live.jpl.nasa.gov/），同时感谢Alex Gardner参与NASA NISAR科学团队。
