The C-band (5.3 GHz) RADARSAT SAR imaged a swath on the earth 460 km wide (in ScanSAR mode) with a pixel size of 50 m, unhampered by clouds or darkness. The satellite data were received and processed into imagery at the Alaska SAR Facility (ASF) in Fairbanks. Sequential pairs of images were then processed by the RADARSAT Geophysical Processor System (RGPS) at the Jet Propulsion Laboratory (JPL) in Pasadena to derive the motion of the sea ice on a 5-km grid by tracking common features in each pair of images. Thus we have a year-long record of the spatial pattern of ice motion and the radar backscatter in the vicinity of the SHEBA site. Ice deformation (divergence, shear) and ice vorticity are computed from the RGPS ice motion products. This dataset contains 4 sea-ice deformation products containing divergence, shear, and vorticity values based on 4 square regions centered on the SHEBA station: 50 x 50 km, 100 x 100 km, 150 x 150 km, and 200 x 200 km. Additionally, there are 4 graphical products, one of each: divergence, shear, vorticity, and area. completed EOL Data Support NSF NCAR Earth Observing Laboratory EOL Data Support PO Box 3000 Boulder CO 80307-3000 datahelp@eol.ucar.edu https://data.eol.ucar.edu/ homepage pointOfContact Harry Stern University of Washington 206-543-7253 Box 355640 Applied Physics Laboratory 1013 NE 40th St Seattle WA 98195 hstern@u.washington.edu pointOfContact GIF: Graphics Interchange Format (image/gif) ASCII: ASCII Text (text/plain) dataset theme Resource Type 2014-10-16 revision 3.1 DataCite Metadata Working Group originator resourceTypeGeneral RADARSAT platform Satellite Oceanography Arctic Sea Ice EARTH SCIENCE > OCEANS > SEA ICE > ICE DEFORMATION Global Change Master Directory (GCMD) 2018-02-27 revision 8.5 National Aeronautics and Space Administration originator none none eng climatologyMeteorologyAtmosphere -170.00000 -130.00000 70.00000 80.00000 1997-11-01T00:00:00Z 1998-10-08T23:59:59Z NSF NCAR Earth Observing Laboratory EOL Data Support PO Box 3000 Boulder CO 80307-3000 datahelp@eol.ucar.edu https://data.eol.ucar.edu/ homepage distributor 1 https://data.eol.ucar.edu/dataset/13.419 https RADARSAT SAR Sea Ice Deformation [H.
