Abstract

The OFIS Model: An Efficient Tool for Assessing Ozone Exposure and Evaluating Air Pollution Abatement Strategies A contribution to subproject SATURN P Sahm and N. Moussiopoulos Laboratory of Heat Transfer and Environmental Engineering, Aristotle University Thessaloniki, 54006 Thessaloniki, Greece Introduction The EU ozone threshold value for the protection of human health (110 |ig/nf, 8-h average) is exceeded substantially (Berge et #/., 1997). Based on measurements at urban stations it was concluded that 80 % of the EU urban population is exposed to these exceedances. What precursor emission reductions are needed in order to reduce sufficiently and cost-effectively tropospheric ozone levels has to be addressed with suitable photochemical simulation models. Until recently, urban photochemistry was analysed either crudely (with simple box models) or by the aid of sophisticated 3-D photoc
