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

         AMSR-E Level-1A observation counts are processed from Level 0 science packet 
         data by the Japan Aerospace Exploration Agency (JAXA). Each half-orbit data 
         granule consists of observation counts, antenna temperature coefficients, 
         offsets for calculating antenna temperatures, calibration temperature counts, 
         land/ocean flags, time, latitude, longitude, and navigation fields in HDF 
         format.

         The data sampling interval is 2.6 msec for each 1.5-sec scan period for the 
         6.9-GHz to 36.5-GHz channels, and 1.3 msec for the 89.0-GHz channel. AMSR-E 
         collects 243 data points per scan for the 6.9-GHz to 36.5-GHz channels, and 
         486 data points for the 89.0-GHz channel. Each swath spans 50 minutes. Data 
         are available via FTP.
