Five one-year air quality simulations over a domain covering Europe have been performed using the CHIMERE chemistry transport model and the EMEP emis-sion dataset for Europe. These five simulations differ only by the representation of the effective emission heights for an-thropogenic emissions: one has been run using the EMEP standard recommendations, three others with vertical injec-tion profiles derived from the EMEP recommendations but multiplying the injection height by 0.75, 0.50 and 0.25, re-spectively, while the last one uses vertical profiles derived from the recent literature. It is shown that using injection heights lower than the EMEP recommendations leads to sig-nificantly improved simulation of background SO 2 , NO 2 and O 3 concentrations when compared to the Airbase station measurements.
