Group: Summary

   This data set contains radar backscatter measurments taken over the Soil 
   Moisture Experiments 2002 (SMEX02) Walnut Creek Watershed area in Iowa, USA. 
   The Airborne Synthetic Aperture Radar (AIRSAR) instrument in POLSAR mode was 
   mounted on a DC-8 aircraft that flew on five days in the study period: 1, 5, 
   7, 8, and 9 July 2002. On each of these days, three distinctive flight lines 
   were flown and six different scenes were collected. Two flight lines were 
   east-west in orientation and were concentrated around the Walnut Creek (WC) 
   watershed. The other line was north-south oriented, and covered both the WC 
   watershed and the regional study area.

   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.
