Group: Summary

   The data set SMEX03 Surface Roughness Data is comprised of data collected over 
   the regional study areas of Alabama, Georgia, and Oklahoma, USA as part of the 
   2003 Soil Moisture Experiment (SMEX03). The experiment was conducted from June 
   2003 through July 2003 at various hydrologic network sites in northern 
   Alabama, at the Little River (LR) watershed in southern Georgia, and at the 
   Little Washita (LW) watershed in south-central Oklahoma. Surface roughness 
   parameters include root mean square (rms) height, correlation length (L), and 
   correlation length function [f(L)]. For each regional study area, surface 
   roughness conditions were photographed using a grid board and the roughness 
   photographs were then digitized in order to derive surface roughness 
   calculations. The total volume for this combined data set is approximately 20 
   KB. 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.
