dataset : SMEX02 SSM/I Brightness Temperature Data, Iowa
SMEX02 SSM/I Brightness Temperature Data, Iowa
The Special Sensor Microwave/Imager (SSM/I) is a seven-channel, four-frequency, linearly polarized passive microwave radiometric system. Data are brightness temperatures given by channel: 85.5 GHz, 37.0 GHz, 22.2 GHz, and 19.3 GHz. The study was conducted between 29 April and 13 July 2002 in the SMEX02 Iowa study area. Data are provided as 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.
