There is a lack of knowledge on sources, properties and effects of organic aerosols in the Arctic, especially during spring when high concentrations or aerosols, Arctic haze, is observed. 

In this pilot project we will

- collect particle samples at VILLUM research station during spring 2015
- investigate aerosol sources and atmospheric processes by analysis of organic molecular tracers in aerosols, using ultrahigh-performance liquid chromatograph coupled to quadrupole time-of-flight mass spectrometer (UHPLC-qTOF-MS)
- determine physical-chemical parameters such as hygroscopic growth, CCN activity, water activity or surface tension of Arctic aerosol samples in order to deduct information on their cloud-forming potential
 

The project also includes a research stay at University of California - Berkeley and experiments using instrument facilities at PNNL, USA.

The results are relevant to understanding aerosol sources and processes in the Arctic during spring.
