Group: Summary

   This data set is part of  the Soil Moisture Experiment 2002 (SMEX02) project, 
   which is associated with the Advanced Microwave Scanning Radiometer - Earth 
   Observing System (AMSR-E) validation project. It consists of Vegetation Water 
   Content (VWC) data. VWC was derived from Normalized Difference Water Index 
   (NDWI), which was derived from Landsat 5 Thematic Mapper (TM) and Landsat 7 
   Enhanced Thematic Mapper plus (ETM+) imagery. The TM satellite data were 
   acquired during select dates in June and July 2002. These data cover the 
   SMEX02 Walnut Creek watershed and the regional Iowa study areas in Iowa, USA. 

   Data are provided as flat binary files and are available via FTP. Data must be 
   divided by 25.5 to obtain the actual vegetation water content in 
   kg/m3.

   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.
