SMEX05 Soil Moisture Network Data: Iowa
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 soil moisture network data collected over the Soil Moisture Experiment 2005 (SMEX05) area of Iowa, USA from 10 June 2005 through 03 July 2005. The total volume of this data set is approximately one megabyte. Data set parameters are soil temperature and volumetric soil moisture. Related measurements for soil salinity and soil water conductivity are included. Data are provided in ASCII tab-delimited text format and Microsoft Excel format, and are available via FTP. The Advanced Microwave Scanning Radiometer - Earth Observing System (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.
