The data set consists of all ERS-2 SAR data acquired by the Alaska Satellite Facility (ASF) operated by the Geophysical Institute of the University of Alaska in Fairbanks. The data set contains 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.
ERS-2 SAR data is restricted to NASA and ESA 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/.
