area of research
chemical transformation of trace components of the atmosphere
• formation of components of atmospheric aerosols
• formation of acidity (H2SO4, HNO3, HONO, -COOH)
• formation of new compounds (not yet detected)
• new chemical mechanisms
in the context of their fate and influence on climate and biosphere

we work in small laboratory reactors ...
... apply such analytical techniques as
UV/Vis spec, HPLC, IC, ESI-MSn
electrochemistry (conductivity, pH, pO2) ...

sky analysis
•analyse in situ chemical composition of aerosols/waters
• new compounds, •
radicals, • nonequilibrium partitioning of sparingly soluble compounds
search for:
• map the distribution of a trace compound, say isoprene, and its descendants along trajectories starting from emission sources
• validate modeling of atmopheric chemistry

•true in situ atmospheric experiments

•disturb the atmosphere locally e.g. inject some components into a cloud
•return to analyse what happened and follow the changes along trajectories
