Precursor distributions, ozone formation and control strategy options for Sydney

Abstract

A simple ozone formation model for the Sydney airshed is presented. This model, in conjunction with the observed precursor distribution, gives ozone concentration distributions which are the same as those obtained from our earlier ozone-precursor relationships. Both the ozone-precursor isopleth plot and the simple model give ozone concentration distributions which compare very well with the ozone concentration distribution obtained from the regional monitoring network. These ozone-precursor relationships have been used to predict ozone-concentration distributions which would result from twenty five different precursor control actions. The results confirm that a hydrocarbon emission reduction strategy is the optimum choice of control route for Sydney.
