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.

   The data set SMEX04 Surface Roughness Data is comprised of data collected over 
   the regional study areas of Arizona, USA and Sonora, Mexico as part of the 
   2004 Soil Moisture Experiment (SMEX04). The experiment was conducted 30 July 
   2004 to 25 August 2004 at various hydrologic network sites in Arizona and 
   Sonora. Surface roughness parameters include root mean square error, 
   correlation length, root mean square error adjusted for slope, and power 
   coefficient.  For each study area, surface roughness conditions were 
   photographed using a grid board and the roughness photographs were then 
   digitized using a SigmaScan pro 4 scanner in order to derive surface roughness 
   calculations. The total volume for this combined data set is approximately 36 
   kilobytes. 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.
