  1. 1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ellen Grace Soroka; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER

  3. 2. Avsättning av Black Carbon i sediment från Odensjön, södra Sverige

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Edward Allison; [2022]
    Nyckelord :Black Carbon; BC; Odensjön; flux; CTO-375; chemo-thermal oxidation; Earth and Environmental Sciences;

    Sammanfattning : Black Carbon är resultatet av ofullständig förbränning av fossila bränslen och biomassa. Partiklarna blir luftburna i samband med förbränning och sprids över hela jorden. Utsläpp och spridning av BC är problematiskt, eftersom partiklarna har stor påverkan på människors hälsa och miljön. LÄS MER

  4. 3. Influences of black carbon levels in the micro-environment inside urban buses

    Kandidat-uppsats, Stockholms universitet/Institutionen för miljövetenskap

    Författare :Anton Dahlberg; [2020]
    Nyckelord :Black carbon; buses; in-cabin; urban air pollution;

    Sammanfattning : Several studies indicate that the cabin of buses is the micro-environment in urban public transport where commuters might be the most exposed to black carbon. Black carbon functions as an indicator of air pollution, which is shown to have harmful impacts on the human body and because it may lead to cancers, systemic inflammation, and cardiovascular diseases, it is listed as one of the top causes to premature deaths, globally.

  5. 4. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

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

    Författare :Ellen Carneheim; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... LÄS MER
