PTR-TOF technology contributes to CLOUD experiment at CERN

New results have been published by the CLOUD team in the prestigious journal „Nature“.

The CLOUD experiment at CERN (European Organization for Nuclear Research) reports a major advance towards solving a long-standing enigma in climate science: how do aerosols – tiny solid or liquid particles suspended in the air – form in the atmosphere, and which gases are responsible? This is a key question in understanding the climate, since aerosols cause a cooling effect by reflecting sunlight and by seeding cloud droplets.

Researchers found out that minute concentrations of amine vapours combine with sulphuric acid to form aerosol particles at rates similar to those observed in the atmosphere. Amines are emitted both from human activities such as animal husbandry, and from natural sources.

The PTR-TOF-MS technology was used to monitor the CLOUD aerosol-chamber by Prof. Armin Hansel and his team, Institute for Ion Physics and Applied Physics of the University of Innsbruck.
