  2. 1. Modeling aerosol-cloud interactions in the Arctic

    Author : Hannah Frostenberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixed-phase clouds; ice nucleating particles; heterogeneous freezing; Arctic; LES-modeling; parameterization;

    Abstract : Clouds have a large impact on Earth’s energy balance, especially in the Arctic. Through their warming or cooling effect on the surface, clouds can play a critical role in the onset of melting and freezing of Arctic sea ice, which itself has a large effect on energy and moisture fluxes between the ocean and the atmosphere.

  4. 2. Aerosol-cloud-radiation interactions in global climate models

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

    Abstract : 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.

  6. 4. Chemical perspectives on aerosol-cloud interactions in the High Arctic

    Author : Karolina Siegel; Claudia Mohr; Annica M. L. Ekman; Ilona Riipinen; Ryan Sullivan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aerosol chemical composition; DMS oxidation; FIGAERO-CIMS; κ-Köhler theory; High Arctic; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Atmospheric aerosol particles have important yet highly uncertain impacts on the Earth’s climate, with the largest uncertainties residing in the interactions between aerosols and clouds. The extent to which aerosols act as cloud condensation nuclei (CCN) depends on the chemical composition and size of the particles. READ MORE

  7. 5. Aerosol–cloud interactions in a warming Arctic

    Author : Linn Karlsson; Paul Zieger; Radovan Krejci; Annica M. L. Ekman; Birgit Wehner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosols; clouds; aerosol-cloud interactions; Arctic; climate; field studies; Environmental Sciences; miljövetenskap;

    Abstract : Atmospheric aerosol particles are small liquid or solid particles suspended in the air. They are present in the atmosphere all around us and affect the planetary energy balance by scattering and absorbing radiation and by interacting with clouds. In model projections of future climate, aerosol–cloud interactions contribute a lot of uncertainty. READ MORE
