Group: Summary

   This data set includes data collected over the Soil Moisture Experiment 2002 
   (SMEX02) area of Iowa, USA, during June and August, 2002. The SeaWinds 
   scatterometer on NASA's QuikScat satellite collected bacscatter data that can 
   be used to infer vegetation and soil moisture. SeaWinds uses a rotating dish 
   antenna with two spot beams that sweep in a circular pattern. The antenna 
   radiates microwave pulses at a frequency of 13.4 gigahertz across broad 
   regions on Earth's surface. Data are provided in binary arrays, digital 
   images, and video (.avi) 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.
