Interpretive Summary:

Technical Abstract: A series of large-scale soil moisture field experiments have been conducted over the past decade. These have been successful at addressing a broad range of science question, focusing technology development and demonstration, and providing educational experiences for undergraduate and graduate students. Soil Moisture Experiments 2003 (SMEX03) will focus on satellite based soil moisture products. The NASA Aqua and Japanese ADEOS-II Advanced Microwave Scanning Radiometer (AMSR) Programs are committed to developing and providing daily soil moisture products. This is the first time that this challenging task has ever been attempted. The wide range of vegetation conditions that have to be dealt with, due to the global coverage and multi-temporal observations, exceed those that have been evaluated in previous investigations. For these reasons, validation is critical to the AMSR soil moisture product development and acceptance. SMEX03 will provide validation data for a wide range of vegetation conditions ranging from well-understood grass and wheat in Oklahoma to new observations of the Amazon rainforests. In addition it will provide a test bed for other new satellite instruments such as the Envisat ASAR and aircraft based prototype satellite instruments. SMEX03 will be conducted at U.S. sites in Oklahoma, Georgia and Alabama in June and July and Brazil in September.
