Possible Applications and Constraints of the ECOSIM Project in the Polish Test Site Tomczak, Zbigniew Pillmann, Werner; Tochtermann, Klaus The ECOSIM project treats about a model-based information and a decision support system for urban environmental management. 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.

Integrating the Process-based Simulation Model DNDC into GIS Huber, Stefan; Bareth, Georg; Doluschitz, Reiner Pillmann, Werner; Tochtermann, Klaus Several trace gases, such as methane, nitrous oxide, nitric oxide, and ammonia, affect global climate change because of their radiative or chemical effects in the atmosphere. 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.
