Group: Summary

   This data set includes data collected over the Soil Moisture Experiment 2004 
   (SMEX04) area of Sonora, Mexico during 1 June to 30 September 2004.  The 
   SeaWinds scatterometer on NASA's Quick Scatterometer (QuikSCAT) satellite 
   collected backscatter data.  Data are provided in Brigham Young University - 
   Microwave Earth Remote Sensing (BYU-MERS) Scatterometer Image Reconstruction 
   (SIR) images and Graphics Interchange Format (GIF) images, 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.
