Interpretive Summary:

Technical Abstract: Soil moisture field experiments have been very successful at addressing a broad range of science question, focusing technology development and demonstration, and providing educational experiences for undergraduate and graduate students. The data have been used in studies that went well beyond the algorithm research, primarily due to an emphasis on developing map-based products. For 2002, a soil moisture field experiment (SMEX02will be conducted that will support the science needs of the NASA Terrestrial Hydrology Program Soil Moisture Mission (EX-4a), the NASA Global Water and Energy Cycle Research Program, the EOS Aqua Advanced Microwave Scanning Radiometer (AMSR), and NOAA-DOD prototype land parameter algorithms utilizing data from the Special Sensor Microwave Imager (SSM/I). The objectives of SMEX02 are to understand land-atmosphere interactions, extension of instrument observations and algorithms to a broader range of vegetation conditions, validation of land surface parameters retrieved from SSM/I and potentially AMSR data, and the evaluation of new instrument technologies for soil moisture remote sensing. The combined objectives will be addressed with ground/aircraft/spacecraft observations over sites in Iowa during the summer of 2002. Plans are being developed for intensive studies to validate AMSR in 2003 that will include sites in Oklahoma, Georgia, and Alabama.
