Explosive volcanic eruptions are natural experiments that can provide unique insights into many of atmospheric processes. Understanding how the climate system responds to volcanic forcing does not only allow testing our understanding of processes relevant to climate change, it can also advance our ability to interpret past records. Although volcanic effects on atmosphere and climate have been a topic of intensive research for several decades, many important processes are still only poorly understood. This contribution will provide an overview of research activities within the recently funded cooperative research project "VolImpact" (DFG Research Unit FOR 2820), which will address several of these insufficiently understood processes. These include the initial development of explosive volcanic plumes, the radiative and chemical effects associated with volcanic stratospheric aerosols, aerosol-cloud interactions, dynamical effects of volcanic eruptions in the troposphere, stratosphere and mesosphere as well as effects on the hydrological cycle.
