An Empirical, Receptor-Based Procedure for Assessing the Effect of Different Ozone Mitigation Strategies

摘要: The paper presents a new receptor-based approach for investigating the effect of different mitigation strategies on surface ozone concentrations. empirical relates measured concentrations to 3-D back trajectories and European precursor emission data (NO x , VOC, isoprene). These are only parameters used as input. Following description method, results two German stations, an urban rural mountain site, described, discussed in detail. For reductions 50% area 0.5 million km2 around station resulted between 10 22% during smog episode, 9 14% summer season. This compares well with CTM results. Increasing reduced emissions above does not lead additional reductions. Application procedure site gives plausible if NO VOC or isoprene is reduced. However, simultaneous reduction leads unlikely increase. Possible reasons this discussed, proposals testing improving method made.
