Abstract
In the present work model simulations with a box model applying typical tropospheric initial conditions for three different scenarios (marine, rural and urban conditions) are performed to model tropospheric chemistry in both the gas and the aqueous phase. The gas phase chemistry is described by RADM2 [1]. For the aqueous phase chemistry a detailed aqueous phase mechanism (CAPRAM, c hemical a queous p hase r adical m echanism) was developed. This mechanism is more extensive than other existing mechanisms, because the oxidation of organic compounds with one and two carbon atoms, an explicit description of radical or iron(III) initiated S(IV)-oxidation, the reactions of radicals and radical anions ·OH, NO 3·,·Cl 2 −,·Br 2 −, and CO 3 −·, and the chemistry of the dissolved transition metal ions (TMI) iron, manganese and copper is treated in detail.
