Chemistry Transport Modeling
A number of pollutants are emitted into the atmosphere by human activities. These activities include burning of fossil and non-fossil fuels, agriculture and the use of chemicals. These substances may be transported over large distances in the atmosphere, where they are chemically modified and finally removed by dry and wet deposition. In high concentrations, many substances are harmful for humans, animals and plants.
Complex three dimensional model systems are the tools that scientist in the department on atmospheric chemistry transport modeling at Hereon use to investigate emissions, transport and fate of pollutants, nutrients and long-living chemicals. The models are applied to reconstruct past conditions, as well as to evaluate scenarios for the future. Ship emissions have become more and more important as a source of pollutants in marine environments and are currently in the focus of our research. Regionally, the North and Baltic Seas and their coastal regions are of particular interest.
