DATA ORGANISATION AND MODELLING EXPERIENCES IN BUDAPEST AIR QUALITY MANAGEMENT

Abstract

In the Budapest Air Quality Management System programme the British Atmospheric Dispersion Modelling System (ADMS-Urban) is to be used. The integrated database demanded consists of different emission sources with their coordinates, meteorological data and surface data. Special pre-processing is needed in case of traffic emission where a traffic flow model and a set of emission factors are used. In case the number of sources exceeds 1500, a simplified approach is used by 1×1 km grids. A combination of grid and individual source impact assessment is also possible. As general schemes are known in this field, the presentation puts emphasis on some major methodological considerations especially in data organisation.
