RADARSAT SAR Sea Ice Motion [Kwok, R. and H. Stern]
https://data.eol.ucar.edu/dataset/13.814

Summary
The Canadian RADARSAT satellite collected 195 synthetic aperture radar (SAR)
images of the SHEBA site between November 1, 1997, and October 8, 1998
(roughly one image every 3-5 days). 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. The
RADARSAT Geophysical Processor System (RGPS) created 184 ice motion products
bundled into one .tar file from 184 sequential pairs of RADARSAT SAR images of
the SHEBA region. The sea ice motion products are accompanied by 4 graphical
products bundled into one .tar file.
