  1. 11. Ice out of Fire : Ice and cloud condensation nucleation of aerosol particles emitted from controlled soot generation and combustion of renewable fuels

    Författare :John Falk; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soot; BC; Immersion freezing; IN; INP; CCN; SPIN; CCNC; MiniCAST; Cold Stage; Cook Stove;

    Sammanfattning : Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. LÄS MER

  3. 12. On the liquid-phase cloud activation of insoluble and slightly soluble particles

    Författare :Maryam Dalirian; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Aerosol-cloud interactions are among the largest sources of uncertainty in understanding climate change and predictions of the future climate. Besides the physical dimensions of aerosol particles, their water-solubility and surface tension are the key properties needed to describe their potential to act as cloud condensation nuclei (CCN).

  4. 13. A large-eddy simulation perspective on Arctic airmass transformation and low-level cloud evolution

    Författare :Antonios Dimitrelos; Annica Ekman; Caballero Rodrigo; Rune Grand Graversen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic; mixed phase clouds; sea ice; Arctic amplification; atmospheric energy transport; CCN; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : The Arctic is currently warming faster than other regions of the Earth. Many processes and feedbacks contribute to the enhanced warming. Among these are the radiative effects of clouds. LÄS MER

  5. 14. Arctic clouds - interactions with radiation and thermodynamic structure

    Författare :Joseph Sedlar; Michael Tjernström; Annica Ekman; Johannes Verlinde; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; stratus; radiation; thermodynamic structure; cloud radiative forcing; seasonal transition; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. LÄS MER

  7. 15. Cloud Droplet Forming Potential of Ageing Soot and Surfactant Particles : Laboratory research and Köhler modelling

    Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :Hygroscopicity; CCN; BC;

    Sammanfattning : Aerosol particles affect Earth’s climate system by scattering and absorbing light. The perturbation of the climate system caused by a change in aerosol configuration due to anthropogenic emissions has recently improved. LÄS MER
