Relationships between local ozone concentrations,reginal proecursor emissons and european atmospheric criculaton patterns

摘要

The effect of changes in anthropogenic precursor emission on ambient ozone concentration is commonly assessed with extensive mdoel calculations.It may ,however,also be deducted from obserations where chemical processes are implicitly included: we use european precursor emission data (EMEP,IER Stutgart),4-day back trajectories (Eruopean Modle.,DWD) and measured ozone ocncentrations at a receptor site for establishing empiricla relations to the relevant precursor emissions undr the flow climatology typical for the receptor.
