1. Small and Large, Charged Molecules in Solution and at Interfaces
Abstract : The influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. READ MORE

2. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds
Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE

3. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols
Abstract : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. READ MORE

4. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe
Abstract : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. READ MORE

5. The Tropospheric Aerosol - Measurements and Modelling. Case studies in Tanzania and Southeast Asia and development of models for size resolved aerosol simulations on the regional scale
Abstract : The tropospheric aerosol is a complex constituent of the atmosphere that has impacts on health and the climate. This thesis presents five different studies from Tanzania, Southeast Asia and Europe dealing with urban measurements of particle mass and elemental composition, regional scale modelling of ozone and particle mass of inorganic aerosols and development of modules for sea salt emissions and size resolved aerosol particles with aerosol dynamical mechanisms implemented in a regional scale chemistry and transport model (CTM).
