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) now considers 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 of not only
the chemical degradation of the simulated volatile organic
compounds but also the contribution of organics to the
growth and fate of (organic) aerosol, with the 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
reproduced well globally, whereas 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.},
