Group: Summary

   Notice to Data Users: The documentation for this data set was provided solely 
   by the Principal Investigator(s) and was not further developed, thoroughly 
   reviewed, or edited by NSIDC. Thus, support for this data set may be limited.

   This data set contains several parameters measured in the Walnut Gulch 
   Experimental Watershed for the Soil Moisture Experiment 2004 (SMEX04). The 
   parameters include volumetric soil moisture, soil temperature, soil 
   conductivity, soil salinity, and surface temperature. Data provided here were 
   collected from 1 July 2004 through 30 September 2004 using in situ soil 
   moisture sensors and radiometric surface temperature sensors. The total volume 
   of this data set is approximately 18 MB. 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.
