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 Normalized 
   Difference Vegetation Index (NDVI) and Normalized Difference Water Index 
   (NDWI) data, derived from Landsat 5 Thematic Mapper (TM) and Landsat 7 
   Enhanced Thematic Mapper plus (ETM+) imagery. The 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 south-central Iowa, USA. 

   Data are provided as flat binary 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.
