Abstract. In this technical note we present the multi-purpose atmospheric
chemistry model MECCA. Owing to its versatility and modular structure,
it can be used for tropospheric as well as stratospheric chemistry
calculations. Extending the code to other domains (e.g. mesospheric
or oceanic chemistry) is easily possible. MECCA contains a
comprehensive atmospheric reaction mechanism that currently includes:
1) the basic O3, CH4, HOx, and NOx
chemistry, 2) non-methane hydrocarbon (NMHC) chemistry, 3) halogen
(Cl, Br, I) chemistry, and 4) sulfur chemistry.
Not only gas-phase chemistry but also aqueous-phase and heterogeneous
reactions are considered. Arbitrary subsets of the comprehensive
mechanism can be selected according to the research objectives. The
program code resulting from the chemical mechanism can easily be used
in any model, from a simple box model to a comprehensive global
general circulation model.
