Group: Summary

   This data set contains measurements collected from flights conducted in June 
   and July 2002 over the Walnut Creek watershed in central Iowa, USA. The study 
   was part of the Soil Moisture Experiment 2002 (SMEX02) and the Soil 
   Moisture-Atmosphere Coupling Experiment (SMACEX), run by Canada's National 
   Research Council (NRC). The aircraft carried numerous sensors, and flew 
   several flights per day along six tracks in the watershed area. Parameters for 
   this data set include air pressure and temperature, dew point and radiometric 
   temperature, greenness index, net radiation, CO2 concentration, 
   wind direction and speed, heat flux, and ozone flux.

   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.
