Data Set ID:

SMEX04 Landsat Thematic Mapper Imagery, Arizona, Version 1

This data set provides imagery developed from Landsat 5 Thematic Mapper (TM) data for use in studying land cover features during the Soil Moisture Experiment 2004 (SMEX04). Three false color images are provided for the regional study areas in Arizona, USA and Sonora, Mexico for 11 June 2004, 29 July 2004, and 30 August 2004. The images are the result of combining TM bands 2, 3, and 4 as blue, green, and red respectively to generate false color composites. Data are provided in Georeferenced Tagged Image File Format (GeoTIFF) 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.
