As part of the Danish strategic research project ECOCLIM: Ecosystems Surface Exchange of Greenhouse Gases in an Environment of Changing Anthropogenic and Climate forcing a model system will be developed. This model system will be based on both terrestrial and marine ecosystems in order to be able to describe the exchange of GHG with main focus on carbon dioxide (CO2) and the exchange above the Danish terrestrial biosphere as well as above Danish waters including fjords. The construction of the model system is based on data from new, existing and previous field experiments and on improved ecosystem and atmospheric models. We will use the model system to 1) quantify the potential effects of climate change on ecosystem exchange of GHG and 2) estimate the impacts of changes in management practices including land use change and nitrogen (N) loads. Here the various model components will be introduced and the scientific questions that we will investigate will be discussed.
