   This data set is part of the Soil Moisture Experiment 2002 (SMEX02). 
   Investigators acquired a series of Advanced Spaceborne Thermal Emission and 
   Reflection Radiometer (ASTER) images from the Terra satellite. Three ASTER 
   scenes were combined in a mosaic and the regional study area extracted to form 
   one image. These data  represent a single point in time; the satellite 
   overpass time was 17.20 GMT on July 1, 2002. The study area is the Walnut 
   Creek Watershed area in Iowa, USA, covering 41.70 to 42.73°N and 93.16 to 
   93.84°W.  These ASTER Level 1B data include three Visible and 
   Near-infrared (VNIR) bands with 15 m spatial resolution of 15 m, six Shortwave 
   Infrared (SWIR) bands with 30 m spatial resolution, and five Thermal Infrared 
   (TIR) bands with 90 m spatial resolution. The data are L1B data with geometric 
   and radiometric correction. The data are in unsigned integer binary files in 
   terms of scaled radiance, one file for each band. Data 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.
