Group: Summary

   This data set provides brightness temperature data acquired during the Soil 
   Moisture Experiment 2003 (SMEX03) by the Special Sensor Microwave/Imager 
   (SSM/I). The study was conducted between 29 April 2003 and 29 September 2003 
   in the SMEX03 Alabama/Georgia study area, between 29 April 2003 and 23 
   September 2003 in the SMEX03 Oklahoma study area, and between 29 September 
   2003 and 28 February 2004 in the SMEX03 Brazil 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.
