Paul C. Stoy

Assistant Professor, Ph.D. 2006, Duke University; B.A. 2001, University of Wisconsin. Surface-atmosphere exchange of water, energy, and trace gases with an emphasis on plot scale measurements and regional & global scale synthesis. Specific interests include quantifying the impacts of land use change and climate change on the surface energy balance, the carbon cycle, and hydrology in temperate, boreal and arctic ecosystems.
