AB: The need for long-term remote sensing observations in different terrain and climatic regions for development/validation of hydrologic models and assimilation methodologies cannot be over-emphasized. Observations at microwave wavelengths are particularly sensitive to near-surface soil moisture. Many studies have been conducted in agricultural terrain such as bare soil, grass, soybean, wheat, pasture, and corn to understand the relationship between soil moisture and microwave remote sensing. However, most of these experiments have been short-term experiments capturing only a part of growing seasons. Microwave, Water, and Energy Balance Experiments (MicroWEXs) are a series of season-long experiments conducted at a 9-acre field site to understand land-atmosphere interactions and microwave observations for growing corn and cotton in North Central Florida. During MicroWEXs, we observed microwave signatures at 4.5 cm (MicroWEX-1through 6) and 20 cm (MicroWEX-5 and 6) using tower mounted radiometer systems, along with co-located concurrent micrometeorological parameters. In addition, we observed detailed soil moisture, temperature, and heat flux profiles at multiple locations, ground water levels, and soil and vegetation parameters throughout the growing seasons. Such extensive, high temporal frequency datasets are being used for understanding physically-based SVAT, crop growth, and microwave remote sensing models and developing novel assimilation technologies to improve model estimates of moisture and energy fluxes at the land surface and in the vadose zone. An overview of various observations during the MicroWEXs and their significance in multidisciplinary studies will be presented.
