Our research intends to understand the tropospheric multiphase system. Model development is based on experimental work in the laboratory and in the field. Lab work utilises state-of-the-art physical and analytical chemistry methods to study gas phase, aqueous phase, organic phase, surface and, alltogether, multiphase phenomena. Field work aims to understand chemical processing and composition of tropospheric particles, clouds, fog and rain in the complex interplay of all compartments involved.

Investigation of oxidation reactions of functionalized hydrocarbons in aqueous solution and phase transfer.
Building on laboratory and field experiments, detailed chemical mechanisms are developed and implemented within numerical models to investigate multiphase atmospheric processes. Specialized modules are continuously developed and integrated to enhance the accuracy and performance of large-scale atmospheric simulations.
