Treatment of Transport in MOGUNTIA

At the IMAU, the program MOGUNTIA has been implemented. MOGUNTIA is a climatological three-dimensional global tropospheric transport model, designed by Zimmermann (1988). The current resolution amounts to l0o x l0o x 100 hPa. The upper layer is located at 100 hPa. The model is used for extensive tropospheric chemistry calculations in which the effects of heterogeneous chemistry and aerosols can be taken into account. The global character of the model has proved to be valuable for example to calculate budgets of ozone (Dentener and Crutzen, 1993; Crutzen and Zimmermann, 1991).
