Environmental Assessment Programme (KÉP): Regional scale atmospheric pollution modelling

(László Bozó)

Human health and ecosystem relevant environmental pollutant can reach distant areas from their emitting sources. When preparing environmental evaluation or impact study, the role of transboundary sources should also be taken into consideration. The most relevant tool is a regional/continental scale transport model, that is able to compute the spatial and temporal variation of concentration and deposition fields of atmospheric pollutants. Most of these models are based on 50 km * 50 km spatial resolution. The Eulerian-type EMEP-model has 20 non-equidistant atmospheric layers and 49 components to investigate the emission, chemical transformation, transport and deposition of sulfur, nitrogen, ozone and its precursors. Input meteorological data are preprocessed using raw data provided by ECMWF. Concerning atmospheric heavy metals (lead, cadmium, arsenic, zinc), the TRACE model is applied which was developed in co-operation of IIASA (International Institute for Applied Systems Analyses) and Hungarian Meteorological Service. In the frame of KÉP project, the environmental loads to the atmosphere, surface water and soil, as well as their interactions with each other, are processed within a unified modelling system.
