Dynamics and Chemistry of Hydrometeors: Final Report of the Collaborative Research Centre 233 “Dynamik und Chemie der Meteore”

"Dynamics and Chemistry of Hydrometeors" is the final Report of the Collaborative research Centre 233 "Dynamik und Chemie der Hydrometeore". Hydrometeors are clouds, fogs and precipitation that is condensed liquid or solid water in the atmosphere. This includes the dissolved and not dissolved "impurities" in droplets, ice crystals, and snowflakes. The report covers modelling of atmospheric cloud dynamics, field research of atmospheric multi-phase systems and laboratory research for reaction kinetics and the improvement chemical analysis. The Research Centre proposes a base for modeling the role of cloud dynamics, micro-physical processes in forming and evaporating clouds, and for chemical reactions between gas phase, liquid phase, and aerosols.
