Satellite-derived high-resolution sea-ice motion in the Southern Ocean, 2015-2019 - ESA Sentinel1 Satellite Data
Sea-ice motion derived from two (partially) overlapping ESA Sentinel1 [S1]A or B scenes. Satellites S1A/B carry C-band (5.405 GHz) Synthetic Aperture Radar [SAR] sensors. For this data set images from the Extra Wide swath (EW) mode of operation (swath width 410 km) have been used. EW mode data are a...
