Urban air quality model for long-term impact assessment
A methodology is presented to assess the effects of long-term meteorological and climatological change on worst case air pollution episodes and air pollution frequency distributions. The methodology requires that the assumptions of the CRES (Centre for Resource and Environmental Studies, Australian National University, Canberra) model developed by Simpson be valid, namely that the air pollution data and available wind speed data are lognormally distributed and the ATDL (Atmospheric Turbulence and Diffusion Laboratory) model is appropriate for long-term means. The approach has been applied to 23 years of acid gas data in Newcastle, Australia, and found to agree well with published data and historical records. Incorporation of the effects of different possible meteorological regimes is seen to be as important as including the effects of changes in source emissions when comprehensive assessment and management of an airshed is sought. 17 references, 4 figures, 3 tables.
