Group: Summary

   This data set is comprised of browse images acquired over the regional study 
   areas of Alabama, Georgia, and Oklahoma USA as part of the 2003 Soil Moisture 
   Experiment (SMEX03). The experiment was conducted from March through July 2003 
   via the Advanced Synthetic Aperture Radar (ASAR) instrument on board the 
   European Space Agency's (ESA) Environmental Satellite (ENVISAT). 
   Cross-polarized C-band ASAR images were acquired in order to obtain a 
   backscatter coefficient measurement over a range of natural vegetation types. 
   However, the images provided here are only browse images and therefore cannot 
   be used to derive backscatter coefficient values. Researchers interested in 
   backscatter coefficient values must obtain the ASAR data. The total volume for 
   this combined data set is approximately 65 megabytes. Data are available via 
   FTP and are provided as JPEG image files and JGW georeference files. Also 
   included and available via FTP are the following types of header files: HAN 
   files, ASCII text files, and INI files.

   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.
