  1. 1. Aerosol deposition to coastal forests: a wind tunnel approach

    Författare :Ausra Reinap; Bo L.B. Wiman; Birgitta Svenningsson; Bo Bergbäck; Lise Lotte Sørensen; Linnéuniversitetet; []
    Nyckelord :NaCl aerosol; dry deposition; climate change; coastal-zone forest; Quercus robur; wind tunnel; edge effect; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

    Sammanfattning : Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. LÄS MER

  3. 2. Primary Marine Aerosol Production : An experimental study based on Arctic Ocean water and a sea water proxy

    Författare :Julia Zábori; Margareta Hansson; Gordon McFiggans; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean; primary marine aerosol; climate change; sea water physical properties; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : This thesis focuses on the interplay between the physical properties of ocean water and primary marine aerosol (PMA) emissions in the context of a rapidly changing Arctic climate. PMAs are an important part of the climate system due to their ability to interact with incoming solar radiation and to influence cloud properties. LÄS MER

  4. 3. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER

  5. 4. Experimental Determination of the Deposition of Aerosol Particles in the Human Respiratory Tract

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; deposition; respiratory tract; health; air pollution; aerosol particle; ultrafine particles; lung; Fysicumarkivet A:000;

    Sammanfattning : BACKGROUND: Aerosol particles have, since the antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution cause at least 100,000 deaths in Europe each year, whereof 5,000 in Sweden. LÄS MER

  7. 5. Investigating parameters governing liquid-phase cloud activation of atmospheric particles

    Författare :Maryam Dalirian; Ilona Riipinen; Ottmar Möhler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CCN activation; surface tension; coated aerosols; black carbon; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosol-cloud interactions are one of the main sources of uncertainties in modeling and predicting the Earth’s climate. To overcome this uncertainty, we need to improve the understanding about the processes and parameters defining how aerosol particles turn into cloud condensation nuclei (CCN) or ice nuclei (IN) to produce cloud droplets or ice crystals.
