Description: Das Projekt "Europaeisches Terrestrisches Oekosystemmodell" wird vom Umweltbundesamt gefördert und von Potsdam-Institut für Klimafolgenforschung e.V. durchgeführt. We propose to develop a comprehensive modular framework for the coupled dynamics of structure and function in natural and semi-natural ecosystems. The framework will link the following subsystems with widely varying time contraints: ecosphere-planetary boundary layer (PBL) interactions, ecosystem CO2 and H2O fluxes, vegetation physiology and phenology, biogeography and vegetation dynamics, detritus and soil organic matter dynamics, and human impact and natural disturbance. The framework will allo simulation at 'patch' scale, or at 'regional' (10-100 km) scale including linkage of patches through the PBL. Comparative trials of modelling approaches to each subsystem will use the full range of available observational and experimental data sources as evaluation tools. The coupled system dynamics will be tested with data from long-term field measurements and experimental programmes. A pilot study will show how the model can be generalized spatially, useing gridded environmental data sets. The project is proposed as an integral component of the TERI with close links to other TERI projects, in order to make best use of new data and modelling activities in Europe as well as adding value to field-based projects. The research will contribute to the long-term IGBP-GCTE goal of developing a dynamic global vegetation model with state-of-the-art representation of physical, physiological and ecological processes and their linkages. Potential applications of such a model include Europe-wide assessment of the potential impacts of long-term (decades to centuries) changes in land use, CO2 and climate on ecosystem functions such as carbon sequestration and fresh water supply.
