Beskrivning

Carbonaceous aerosols, i.e. aerosols composed by carbon, have been shown to have impacts on earth’s climate. Aerosols are both having a cooling and heating effect on the climate, thus the uncertainties regarding the climatic net effect are high.

I am studying atmospheric aerosols with the aim to improve the source apportionment and source characterization of carbonaceous aerosols. Aerosols can be emitted from various sources as combustion of fossil fuels, combustion of biofuels, emissions from plants etc. Aerosol sampling takes place on our measurement station, Vavihill, which is located 172 m.a.s.l. on the Söderåsen in Scania. I then use techniques such as thermo-optical analysis (TOA), 14C-measurements, tracer molecules (levoglucosan), optical measurements and stable isotope analysis (δ13C, δ15N) to deduce the sources of carbonaceous aerosols.

Hopefully, the generated data can be used in climate models to lower the overall uncertainty of the climatic effects. Another aim is that the data can be used to direct regulatory measures in order to constrain emissions of harmful carbonaceous aerosols.
