Group: Summary

   This data set includes air temperature, vapor pressure, wind speed, and 
   brightness temperatures taken at 12 flux towers as part of the Soil Moisture 
   Experiment 2002 (SMEX02). This study was conducted during June and July 2002 
   in the  Walnut Creek watershed in south-central Iowa, USA. The flux towers 
   contained humidity and temperature probes, infrared thermometers, and 
   anemometers. Data were recorded every 10 minutes from 06 June through 25 July 
   2002 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.
