      abstract     = {Abstract. An updated and expanded representation of
                      organics in the chemistry general circulation model EMAC
                      (ECHAM5/MESSy for Atmospheric Chemistry) has been evaluated.
                      First, the comprehensive Mainz Organic Mechanism (MOM) in
                      the submodel MECCA (Module Efficiently Calculating the
                      Chemistry of the Atmosphere) was activated with explicit
                      degradation of organic species up to five carbon atoms and a
                      simplified mechanism for larger molecules. Second, the
                      ORACLE submodel (version 1.0) considers now condensation on
                      aerosols for all organics in the mechanism.
                      Parameterizations for aerosol yields are used only for the
                      lumped species that are not included in the explicit
                      mechanism. The simultaneous usage of MOM and ORACLE allows
                      an efficient estimation, not only of the chemical
                      degradation of the simulated volatile organic compounds, but
                      also of the contribution of organics to the growth and fate
                      of (organic) aerosol, with a complexity of the mechanism
                      largely increased compared to EMAC simulations with more
                      simplified chemistry. The model evaluation presented here
                      reveals that the OH concentration is well reproduced
                      globally, while significant biases for observed oxygenated
                      organics are present. We also investigate the general
                      properties of the aerosols and their composition, showing
                      that the more sophisticated and process-oriented secondary
                      aerosol formation does not degrade the good agreement of
                      previous model configurations with observations at the
                      surface, allowing further research in the field of
                      gas-aerosol interactions.},
