Group: Summary

   This data set combines data for several parameters measured for the Soil 
   Moisture Experiment 2002 (SMEX02). The parameters include bulk density, 
   gravimetric and volumetric soil moisture, and surface and subsurface soil 
   temperature. This study was conducted during June and July 2002 in the Walnut 
   Creek watershed in south-central Iowa, USA. Data were collected in crop 
   fields, using a variety of methods and sensors (manual soil samples for bulk 
   density and gravimetric soil moisture data, infrared pyrometers for surface 
   and subsurface soil temperature, and impedance probes for volumetric soil 
   moisture). Data are provided in ASCII text 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.
