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

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Maryam Dalirian; Ilona Riipinen; Ottmar Möhler; [2018]
    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.

  3. 3. Aerosol-cloud-radiation interactions in global climate models

    Detta är en avhandling från Stockholm : Department of Meteorology, Stockholm University

    Författare :Lena Frey; Frida A.-M. Bender; Gunilla Svensson; Laura Wilcox; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aerosols; clouds; global climate models; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Clouds can reflect, absorb and re-emit radiation, thereby inducing a cooling or warming effect on the climate. However, the response of clouds to a changing climate is highly uncertain and the representation of clouds in state-of-the-art climate models remains a key challenge for future climate projections.

  4. 4. Aerosol-water interaction at sub and super-saturated regimes From small scale molecular mechanisms to large scale atmospheric models

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Narges Rastak; Ilona Riipinen; Maria Kanakidou; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Sciences; miljövetenskap;

    Sammanfattning : The term “atmospheric aerosol” refers to solid or liquid particles suspended in the atmosphere. Atmospheric aerosols influence the Earth’s energy budget directly by scattering and absorbing radiation (known as the direct aerosol effect) and indirectly by acting as cloud condensation nuclei (CCN) and ice nucleating particles and thereby modifying cloud properties (known as the indirect aerosol effect).

  5. 5. Molecular-Level Investigations of Water-Organic Systems of Atmospheric Relevance

    Detta är en avhandling från Göteborgs universitet

    Författare :Sofia M. Johansson; Göteborgs universitet.; Gothenburg University.; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EMB method; desorption kinetics; water uptake; organic surfaces;

    Sammanfattning : It is known that aerosol particles may have warming and/or cooling effects on the climate and negative health effects that depend on their chemical and physical properties. However, current understanding of atmospheric particles’ effects is poor due to the diversity of their constituents and associated variations in properties. LÄS MER
