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 includes brightness temperature and soil moisture data acquired 
   with the Polarimetric Scanning Radiometer (PSR) instrument, an airborne 
   microwave imaging radiometer developed and operated by the National Oceanic 
   and Atmospheric Administration (NOAA) Environmental Technology Laboratory. 
   C-band and X-band measurements were taken 05 August through 26 August 2004 
   over the Soil Moisture Experiment 2004 (SMEX04) regional study areas of 
   Arizona, USA and Sonora, Mexico. The PSR/CX band radiometer was chosen for 
   this study due to its similarity with the low-frequency channel of the 
   Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) 
   instrument on the NASA Aqua satellite. 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.
