Project Details


The overall aims of the project are:

Reveal the exact molecular cluster formation mechanisms that explains the observed new particle formation (NPF) over the Boreal forest and in the polluted air in China.

To gain a fundamental understanding of the peroxy radical autoxidation that leads to Highly Oxygenated organic Molecules (HOM) at different temperatures and NOx concentrations.

Improve our knowledge about the Continental-Biosphere-Aerosol-Cloud-Climate (CoBACC) feedback loop and how it is influenced by anthropogenic emissions.
