Group: Summary

   The NASA scatterometer (NSCAT) provided normalized radar cross section 
   (sigma0) measurements of the Earth's surface. While originally designed for 
   wind observation, scatterometer sigma0 measurements have proven useful in a 
   variety of land and ice studies. To aid in the application of these 
   measurements, Brigham Young University (BYU) has prepared this dataset 
   consisting of enhanced resolution images generated from NSCAT sigma0 
   measurements.

   This data set contains images from 16 regions around the globe. Images are 
   made from NSCAT Level 1.5 data (geo-located sigma0 cells) and processed using 
   the BYU SIRF algorithm. To produce the highest possible spatial resolution as 
   well as to ensure full coverage over the images, multiple orbit passes are 
   combined. This data set also contains ASCII ice extent files from the Arctic 
   and the Antarctic. The study period was from 15 September 1996 to 26 June 1997.

   The parameters provided in the images include polarization, geographical 
   region, time span, image type, and reconstruction technique. These data are 
   available via FTP.
