Sensitivity of ozone production to VOC and NOx emissions. A case study with the box-model BAYROZON

A box-model for the prognosis of tropospheric ozone is used to assess the sensitivity of simulated peak ozone concentrations to local VOC and NOx emissions. Distinction is made between biogenic and anthropogenic emissions. The study is performed for a rural and an urban area in Bavaria in July. Main outcome is that in the urban area much less relative increase in emissions is necessary to produce drastically high ozone concentrations than in the rural area, although the simulated concentrations of ozone were higher in the rural area than in the urban area.
