Surface Water Prize - 10th Award


Dennis Baldocchi – University of California, Berkeley, USA

Dr. Baldocchi’s work involves the development of effective models to understand, evaluate and predict evapotranspiration and water-use efficiency in various environments under climate change conditions. Lines of inquiry revolve around quantifying the fluxes of greenhouse gases (e.g. water vapor, carbon dioxide, methane) in ecosystems that receive water excess or water deficiency, advancing our scientific knowledge of the hydrological cycle.
