SMEX03 Soil Climate Analysis Network (SCAN): Alabama

This data set contains measurements taken during the Soil Moisture Experiment 2003 (SMEX03) from 1 June 2003 to 31 July 2003 from sensors at 10 Soil Climate Analysis Network (SCAN) stations located in northern Alabama and southern Tennessee, USA. Parameters measured include Precipitation, air temperature, solar radiation, wind speed, wind direction, relative humidity, soil moisture, soil temperature, soil salinity, and soil dielectric constant. Data are provided as tab-delimited ASCII text 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.
