Description
Invited lecture/speaker Titel: The Cosmics Leaving OUtdoor Droplets (CLOUD) experiment Abstract: The formation of nanoparticles from gaseous precursors is frequently observed in the global atmosphere. Model estimates suggest that new particle formation contributes roughly 50% of aerosol particles to the budget of cloud condensation nuclei. New particle formation is thus considered an important mechanism affecting the indirect aerosol radiative forcing of global climate. The Cosmics Leaving OUtdoor Droplets (CLOUD) experiment aims at the identification and quantification of physico-chemical mechanisms leading to new particle formation under precisly controlled chamber conditions. Experiments are performed at the CLOUD chamber, a 26 m³ stainless steel tank located at the CERN synchrotron in Geneva, Switzerland. The unique facilities available at CERN allow us to simulate nanoparticle formation under ambient conditions and investigate potential influences of cosmic radiation. In this presentation I will give an overview of the CLOUD experiment and present recent results of climate relevance.| Period | 4 Nov 2016 |
