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).
