The OFLS model:an efficient tool for assessing ozone exposure and evaluating air pollution abatement strategies

摘要

The Ozone Fine Structure(OFIS) model describes transport and chemical transformation processes in an urban plume at very low computational effort.This newly developed Eulerian model may be used for calulating ozone levels for individual situations as well as for deriving ozone exceedance statistics based on large-scale meteorological and long-range transport information over a longer time period.Results are presented from the application of the OFIS model to Stuttgart for the period April to both the absolute maximum ozone values and conclusions regarding the influence of assumed ozone emission reductions on the scale to be drawn.
