Study the terrestrial biosphere and the ways ecosystems influence the water cycle. Investigate water, carbon, and energy fluxes within the Earth system from a hands-on experimental approach and through exposure to land-surface and climate models. Includes hydrology, Earth science, environmental engineering, ecology, biology, and climatology. Geological Sciences 390E and 391 (Topic: Ecohydrology/Biometeorology) may not both be counted. Three lecture hours a week for one semester.
