We investigate the kinetics of multiphase chemical processes and assess their contribution to the reduction of model biases. We develop kinetic models for the transformation of trace components which affect the oxidation capacity and aerosols in the atmosphere.

We investigate the impact of tropospheric aerosols on air quality and of aersol-cloud interactions on climate. We develop and apply numerical algorithms for aerosol thermodynamics and formation of cloud droplet and ice crystals.

We perform chemical weather forecasts and provide numerical analysis for particular events and field missions. We apply and develop advanced data assimilation methods for optimizing emissions and investigate predictability and observability.

We investigate the interactions of atmospheric composition with weather and climate. We improve the model representation of surface-atmosphere exchanges and port atmospheric chemistry submodels to GPU-based supercomputers.
