We provide21 sample products ofMEaSUREs ITS_LIVE Sentinel-1 Image-Pair Glacier and Ice Sheet Surface Velocities: Version 2 in three test regions of Greenland Ice Sheet.The full archive of version 2 ITS_LIVE products (including image pair maps, data cubes and mosaics) from Sentinel-1as well as other optical sensors (Landsat-4/5/6/7/8 and Sentinel-2) can be found at the ITS_LIVE project website: https://its-live.jpl.nasa.gov . 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 ascendingimage pairs Region 3 (72.48N, 35.87W; central south of interior Greenland): 10 descendingimage pairs and 1 ascending image pair This serves as asupplementary dataset for the companion journal article submitted to Earth System Science Data (to appear).
