Group: Summary

   The Special Sensor Microwave/Imager (SSM/I) is a seven-channel, 
   four-frequency, linearly polarized passive microwave radiometric system. Data 
   are brightness temperatures given by channel: 85.5 GHz, 37.0 GHz, 22.2 GHz, 
   and 19.3 GHz. The study was conducted between 29 April and 13 July 2002 in the 
   SMEX02 Iowa study area. Data are provided as ASCII text files and are 
   available via FTP.

   These data were collected as part of a validation study for the Advanced 
   Microwave Scanning Radiometer - Earth Observing System (AMSR-E). AMSR-E is a 
   mission instrument launched aboard NASA's Aqua Satellite on 04 May 2002. 
   AMSR-E validation studies linked to SMEX are designed to evaluate the accuracy 
   of AMSR-E soil moisture data. Specific validation objectives include assessing 
   and refining soil moisture algorithm performance; verifying soil moisture 
   estimation accuracy; investigating the effects of vegetation, surface 
   temperature, topography, and soil texture on soil moisture accuracy; and 
   determining the regions that are useful for AMSR-E soil moisture measurements.
