Abstract

In this study we demonstrate how the combination of impacts and contributions can help to understand the response of the atmospheric chemistry on an emission reduction. As an example, we discuss simulation results for Europe from a global-regional chemistry-climate model with source apportionment method. In these simulations we varied the land transport emissions systematically between 25 and 175 %. In most European regions the ozone mixing ratios (e.g. the impacts) vary only slightly, while the contributions of the mitigated source decrease, while contributions of unmitigated sources increase. This demonstrates how the combination of both methods can help to put pressure on unmitigated sources as they contributions increase.
