Overview
- Analysis of filter samples from a series of chamber experiments combining biomass burning emissions with dust particles.
- Biogenic and anthropogenic volatile organic compounds (VOCs) are emitted to the atmosphere and get oxidized through gas-phase chemical reactions to secondary organic aerosol (SOA) precursor compounds that can condense on surfaces.
- The application of atmospheric simulation chambers allows for the investigation of aerosol processing over a longer period of time.
- In a combined study, the interaction between added dust and biomass burning aerosols were investigated in early 2026.
Tätigkeiten / Aufgaben
- Specific biomass burning aerosols were introduced in the chamber alongside varying amounts of dust aerosols.
- Furthermore, the resulting mixed aerosol was subjected to photochemical oxidation, leading to formation of SOA.
- To better understand the decreased SOA formation rate, filter samples of this study should be analyzed for the total peroxide content of the organic fraction as well as the TMI contents.
