AB: Accurate estimates of soil moisture have wide spread applications in the areas of hydrology and atmospheric sciences. Prior experiments have demonstrated the capabilities of estimating soil moisture using remotely sensed measurements collected from satellite and aircraft platforms. Additional testing is required over different geographic settings and for newly developed sensors. In the summer of 2003 a large scale experiment was conducted to support this testing. Field sites were located in Georgia, Alabama, and Oklahoma in the U.S., and in Brazil. At the Georgia U.S. site, soil and plant samples were collected over a 50 by 75 km region covering a range of soil types from sands to sandy-loams and row-crop, pasture, and forest vegetation covers. Measurements were collected for the period from June 23, 2003 to July 2, 2003. Daily in situ soil moisture measurements were taken and plant and soil samples collected for oven drying and determination of moisture content. In addition, continuous in situ soil moisture measurements were made at 20 different sites throughout the coverage area. A wide soil moisture variation was observed both over the study period and from site to site. The data collected will support the EOS Aqua Advanced Microwave Scanning Radiometer (AMSR) Project and provide a basis for testing other remotely sensed data.
