Group: Summary

   The SeaWinds on QuikSCAT scatterometer provides normalized radar cross section 
   (sigma-0) measurements of the Earth's surface. While originally designed for 
   wind observation, scatterometers have proven useful in a variety of land and 
   ice studies. To aid in the selection of regions and time periods for study, 
   Brigham Young University (BYU) has produced this global sigma-0 browse 
   product. This product consists of spatial and temporal averages of QuikSCAT 
   Level 1B sigma-0 values over  one-day periods from 19 July 1999 to the present.

   This data set consists of sigma-0 browse images for the entire globe, the 
   northern hemisphere, and the southern hemisphere. The global images are 
   rectangular latitude/longitude grids covering the entire globe with a 
   resolution of 5 pixels/deg, or about 22.5 km/pixel at the equator. It suits 
   mid-latitude regions but distorts polar regions. Hence, separate hemispheric 
   products are created for high-latitude regions. Those images are polar 
   stereographic projections using a 70 degree reference latitude with a nominal 
   grid size of about 22.5 km. The polar views include only measurements above a 
   high latitude cutoff of 52 degrees. These data are available via FTP, on CD-R 
   and on 8 mm tape.
