Received: 21 January 2013 – Published in Atmos. Chem. Phys. Discuss.: 08 February 2013 Abstract. Five one-year air quality simulations over a domain covering Europe have been
performed using the CHIMERE chemistry transport model and the EMEP emission
dataset for Europe. These five simulations differ only by the representation
of the effective emission heights for anthropogenic emissions: one has been
run using the EMEP standard recommendations, three others with vertical
injection profiles derived from the EMEP recommendations but multiplying the
injection height by 0.75, 0.50 and 0.25, respectively, 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
significantly improved simulation of background SO2, NO2 and O3
concentrations when compared to the Airbase station measurements.
