Description: The PhD position will have a research focus on developing a molecular-level understanding of key processes that are of importance for the occurrence and properties of secondary organic aerosol and organic nitrates (ON). This project includes both fieldwork and laboratory experiments using high-resolution mass spectrometry, and to some extent chemical modelling. Specifically, the candidate will



  *   perform both ground-based and airborne observation with an unmanned aerial vehicle (UAV)-based sampling platform to detect chemicals for both urban and rural environments.
  *   perform laboratory experiments to constrain physiochemical processes responsible for the SOA and ONs' formation and evolution
·        use the obtained knowledge from field observation and lab experiments in models to better assess how ONs influence regional air quality.

The PhD education includes the development of skills and knowledge in general tools applicable to the research. E.g. one will achieve detailed knowledge within advanced mass spectrometry and data analysis using programming software such as of Python, MatLab, or similar. For mechanistic evaluation the candidate will use kinetic modelling for use in chemical transport models. Any pre-knowledge using these tools are beneficial but not a requirement. The research topic is within atmospheric chemistry implying applicants would benefit from having a background in chemistry or alternatively within physics, geosciences, or environmental science.


We think the right candidate will fit in to our dynamic group and the Scandinavian way of doing excellent research!
