Objectives and Goals

The overall objective:


is to construct an integrated model system including terrestrial, marine and atmospheric components that can be used to quantify surface exchange of GHG (green house gasses).


We will use the system to estimate the annual surface flux of CO2 (carbondioxide) and CH4 (methane) in Denmark.


The system will be used to study the effects of management scenarios affecting both land use and N load and it will form basis for more detailed studies of climate change scenarios.


In order to do this the development of a new parameterization of the surface exchange of CO2 and CH4 over enclosed seas and fjord systems is included in the project.



The Scientific objectives:


Identify and quantify physical, chemical and biological processes controlling the air-sea exchange of CO2 and CH4.


Quantify the sinks and sources controlling the atmospheric concentration of CO2 and CH4 and estimate their budgets including uncertainties for Danish terrestrial and marine surfaces under current conditions.


Study the effect of climate change parameters on the surface flux and C-GHG emissions


Investigate the effect of changed land use and N load on C-GHG emissions.



The main goals:


- To increase the understanding of the atmosphere/ecosystem exchange of greenhouse gasses (especially carbon containing compounds in the aquatic ecosystems).

- To develop a model, which can be used to investigate the human and climatic impact on emissions of greenhouse gasses methane (CH4) and carbondioxide (CO2) from a natural ecosystem.

The project will contribute to an improved understanding of the processes, and also use the knowledge gained to make an estimate of the contribution from the natural Danish ecosystems to the emissions of greenhouse gasses.

Furthermore the project will perform a specific analysis of the impact of selected climatic scenarios on the exchange of greenhouse gasses.


ECOCLIM will be carried out in corporation with the already existing Short-lived Climate Force Centre, CRES, under the Strategic Research Council.
