Group: Summary

   The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) 
   instrument on the NASA Earth Observing System (EOS) Aqua satellite provides 
   global passive microwave measurements of terrestrial, oceanic, and atmospheric 
   variables for the investigation of water and energy cycles.

   This Level-3 gridded product (AE_SI6) includes brightness temperatures at 89.0 
   GHz. Data are mapped to a polar stereographic grid at 6.25 km spatial 
   resolution. This product is an intermediate product during processing of 
   AMSR-E Level-3 sea ice products at 12.5 km and 25 km resolution. All variables 
   include daily average, daily ascending and descending horizontally and 
   vertically polarized brightness temperatures. Data are stored in HDF-EOS 
   format and are available from 01 June 2002 to 3 October 2011 via FTP.
