  1. 26. Atmospheric soot particle transformation from urban to rural

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Fredrik Johansson; [2018]
    Nyckelord :Aerosol; soot; atmosphere; Physics and Astronomy; Earth and Environmental Sciences;

    Sammanfattning : The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (CCNC) and a NOx-analyzer.
