Our research group develops novel instrumentation to characterise fundamental properties of atmospheric aerosol particles that are relevant to climate and health. Both intensive field experiments as well as systematic long-term observations of aerosol parameters contribute to an improved understanding of the sources, the transformation, and the life-cycle of atmospheric aerosol particles.
Our group is conducting continuous long-period measurements of the atmospheric aerosol over many years. Thereby, a wide range of spatial scales is covered, from local measurement sites up to global scale. (Picture: CARIBIC aerosol inlet at the lower aircraft fuselage of the Lufthansa Airbus A340-600.)
Aerosol measurements in urban areas yield help improve our knowledge on the exposure of residents to fine and ultrafine particles. The characterisation of ultrafine particles in the vicinity of urban sources, such as car traffic, is an important feature of our studies.

Our group develops novel methods to characterise the water uptake of atmospheric aerosol particles. Knowledge of the water uptake is essential to describe the real state of particles in the atmosphere, and their corresponding optical properties.
