The data set consists of all RADARSAT-1 SAR data acquired by the Alaska Satellite Facility (ASF) operated by the Geophysical Institute of the University of Alaska in Fairbanks. The data are global in extent, containing an abundance data collected within the ASF station mask, approximated by a 3000 km radius circle centered on Fairbanks, and within the McMurdo station mask, approximated by a 3000 km radius circle centered on McMurdo Station, Antarctica.
RADARSAT-1 SAR data is restricted to NASA approved investigators. To become an approved user, you will need to submit a short proposal to NASA. The guidelines for the proposal and submission instructions can be found at http://www.asf.alaska.edu/.
