	            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 land, ocean, and atmospheric 
	            variables for the investigation of water and energy cycles.

This Level-3 
	            gridded product (AE_SI25) includes brightness temperatures at 6.9 through 89.0 
	            GHz and sea ice concentrations. Data are mapped to a polar stereographic grid 
	            at 25 km spatial resolution. All variables include daily ascending averages, 
	            daily descending averages, and daily averages. Data are stored in HDF-EOS 
	            format and are available from 01 June 2002 to 3 October 2011 via FTP.
