Group: Summary

   The parameters for this data set include gravimetric and volumetric soil 
   moisture, bulk density, and soil temperature. This data set is part of the 
   Soil Moisture Experiment 2002 (SMEX02). The SMEX studies are designed to 
   evaluate, among other things, the accuracy of AMSR-E soil moisture data.

   This study was conducted during June and July 2002 in the area around Ames, 
   Iowa, USA. Data were collected in crop fields using a variety of methods and 
   sensors: manual soil samples for gravimetric and bulk density data, infrared 
   pyrometers for soil moisture, and hydra probes for soil moisture and 
   temperature.

   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.
