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 soil temperature, soil moisture content, and leaf water 
   content data obtained over the Barreiras region of Brazil as part of the Soil 
   Moisture Experiment 2003 (SMEX03). An extensive collection of photographs 
   documenting the regional study areas is also included. Soil and leaf samples 
   were collected from 2 through 8 December 2003 and photographs were obtained 
   throughout the field campaign conducted throughout December 2003. The 
   Barreiras region is located in the western part of the Bahia State, Brazil, 
   and presents a mixture of Cerrado and Caatinga vegetation covers. Cultivated 
   pastures and extensive annual crops such as soybean, maize, and cotton are the 
   major land use classes found in the regional study area. Twelve sampling sites 
   were selected based on a Landsat Thematic Mapper (TM) scene and on two 
   preliminary field surveys conducted in early 2003. Meteorological stations 
   were installed in three sampling sites during the entire campaign. The volume 
   of the data set is approximately 50 megabytes. Data are provided in a single 
   spreadsheet file and images are provided as JPEG files. Data 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.
