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 Advanced Microwave Scanning Radiometer - Earth 
   Observing System (AMSR-E) Level-3 daily measurements of surface soil moisture 
   and vegetation/roughness water content interpretive information, as well as 
   brightness temperatures and quality control variables. Ancillary data include 
   time, geolocation, and quality assessment. Input brightness temperature data, 
   corresponding to a 56 km mean spatial resolution, are resampled to a global 
   cylindrical 25 km Equal-Area Scalable Earth Grid (EASE-Grid) cell spacing. 
   Data have been spatially subsetted to the SMEX03 study areas in Alabama, 
   Georgia, and Oklahoma, USA and Brazil. The study period covers 1 April to 31 
   August 2003 for study areas in the USA and 6 November to 31 December 2003 for 
   the Brazil study area. Total volume for this data set is approximately 70 MB. 
   Data are stored in HDF-EOS format 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.
