I am currently an associate scientist at the National Center for Atmospheric Research. During my ASP post-doctoral fellowship at NCAR, I studied statistical downscaling of weather and climate models, snow measurement by a scanning laser system and geodetic quality GPS recievers, solid precipitation measurement, and of course, soil hydraulic properties. My dissertation looked at the relationship between soil hydraulic properties and surface temperature. Soil hydraulic properties control the movement of water within the soil. This in turn partitions rainfall into runoff, infiltration, and evapotranspiration (ET). Soil hydraulic properties are important parameters in climate models, weather prediction, flood forecasting, and aquifer recharge studies. However, the spatial distribution of these properties is very poorly understood. I hope to use the relationship between surface temperatures and soil hydraulic properties to determine hydraulic properties from remotely sensed surface temperatures.
