SMEX03 Soil Texture Data: Alabama

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 ancillary data file provides soil texture classes for Soil Climate and Analysis (SCAN) sites in northern Alabama, USA associated with the Soil Moisture Experiment 2003 (SMEX03). Soil texture measurements were obtained for the top layer of the soil at eight United States Department of Agriculture (USDA) SCAN sites during June and July 2003. Data are provided in a single 1 KB ASCII text file 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.
