Abstract

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. There are 195 images from which two sub-images were extracted, with the SHEBA station at the center of each. One sub-image was at the original spatial resolution of 50 meters per pixel, and 800 x 800 pixels (40 x 40 km). The other sub-image was spatially averaged to 250 meters per pixel, and was also 800 x 800 pixels (200 x 200 km). The two sets of 195 sub-images are bundled into two .tar files. Additionally, there is an animated GIF file of each sequence of 195 sub-images.
