The objective of the present project is the development of a cloud module which combines a complex multiphase chemistry with detailed microphysics. The description of both components is given for a fine-resolved drop spectrum. An efficient numerical solution of the entire complex model strongly requires the development of new numerical models (Wolke et al., 2000). The influence of simplifications within single components and the kind of their coupling on the simulation results will be investigated for different tropospheric situations. In the framework of the joint project, techniques will be provided and tested which allow the description of complex multiphase chemistry and of detailed microphysics in multidimensional chemistry-transport models. The development is performed in close cooperation with the joint cloud experiment project FEBUKO (Herrmann et al.).
