	         gmd:Abstract:  
	
	            This document pertains to two data sets: AMSR-E/Aqua Daily EASE-Grid 
	            Brightness Temperatures (NSIDC-0301) and AMSR-E/Aqua Daily Global 
	            Quarter-Degree Gridded Brightness Temperatures (NISDC-0302). 

The Advanced 
	            Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on 
	            the NASA EOS Aqua satellite provides global passive microwave measurements of 
	            the Earth. NSIDC produces AMSR-E gridded brightness temperature data by 
	            interpolating AMSR-E data (6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, 
	            and 89.0 GHz) to the output grids from swath space using an Inverse Distance 
	            Squared (ID2) method. AMSR-E/Aqua L2A Global Swath Spatially-Resampled 
	            Brightness Temperatures (AE_L2A) input source data are used.

These data are 
	            provided in three EASE-Grid projections (north and south Lambert azimuthal and 
	            global cylindrical) at 25 km resolution, and in one global cylindrical, 
	            equidistant latitude-longitude projection at 0.25 degree (quarter-degree) 
	            resolution. For both data sets, spatial coverage is global, data are daily, 
	            and coverage begins 19 June 2002 and ends 27 September 2011. 

Data are 
	            provided via FTP. Brightness temperature data (in tenths of kelvins) are 
	            two-byte unsigned integers and time files are two-byte signed integers.
