Deciphering cloud nucleation
Particle growth in the atmosphere
Aerosols are crucial to climate, since water condenses on these particles – the first step in cloud formation. Experiments in the CLOUD chamber at CERN, in which different atmospheric conditions can be created, and at the Jungfraujoch Research Station, have now shown that natural sources also have an unexpectedly important role to play in this. The results, which were presented in three articles in the journals "Nature" and "Science", improve our understanding of cloud formation; this, in turn, enables climate developments to be described much more precisely.
