It integrates data acquisition and monitoring systems, GIS, and dynamic simulation models in flexible client-server architecture based on standard protocols. The first phase of the ECOSIM project consists in a detailed project plan, a quality and a dissemination plan, a range of technical specifications, and an initial ECOSIM Demonstrator. The second project phase concentrates on the implementation of the Demonstrator at the three validation sites Athens, Berlin, Gdansk.

An important source of the four trace gases is soil. Agricultural land-use imposes a great deal of disturbance on soils by farming practices leading to elevated trace gas emissions. To assess emissions at regional scale we developed the software DNDC-GIS which integrates the mechanistic trace gas simulation model DNDC in a geographical information system (GIS). Additionally, to overcome the lengthy computation times, we implemented a load balancing module which allows deploying computational resources in a local-area network.
