Research Interests: microwave remote sensing, land surface hydrology
Brief description of current research:
Soil moisture provides plants with water, and also influences the spatial variation of precipitation and the amount of precipitated water that infiltrates into the soil. My research group's long-term goal is to develop models that allow the use of satellite microwave remote sensing to map soil moisture on both local and global scales. To accomplish this goal, we perform field experiments to test numerical models of terrestrial microwave radiation and models which predict the transport of energy and moisture among the soil, vegetation, and atmosphere. Along with colleagues at Iowa State, the USDA ARS National Soil Tilth Lab, and the University of Iowa, we maintain the Iowa Validation Site, a NASA-sponsored long-term remote sensing experiment site near the ISU campus.
