Aerosol-Cloud Interaction

Process Studies on Small Spacial and Temporal Scales

Basic process understanding and a sufficient data basis on the interaction between aerosols, clouds and radiation are essential for the improvement of future weather and climate predictions. We investigate the effect of activation and freezing processes and turbulent mixing processes on the microphysical and radiative properties of clouds as well as on cloud extend and their life cycle. 

Chemical multiphase processes in clouds, fog and mist modify the chemical composition and thus the physical properties of tropospheric aerosols on all scales up to the global scale. In order to quantify their environmental relevance and to project their effects in coupled chemistry transport models in an adequate form, detailed and combined laboratory-, field-, and modelling process studies are essential.
