Current research and/or projects Development, application and implementation of 1) terrestrial ecosystem models and 2) surface hydrological models within the framework of earth system models Application of earth system models to investigate future emissions scenarios and their effect on atmospheric CO2 concentration Use of earth system models to make quantitative projections of future state of the terrestrial biosphere Evaluation of feedbacks between the climate and the terrestrial biosphere Use of climate models to investigate effect of climate change on hydrology
