  2. 1. Cloud Studies with the Droplet Aerosol Analyzer

    Author : Maria Berghof; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud; Aerosol; DAA;

    Abstract : Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. READ MORE

  4. 2. Investigating aerosol effects on stratocumulus clouds through large-eddy simulation

    Author : Ines Bulatovic; Annica Ekman; Caroline Leck; Ilona Riipinen; Daniel Grosvenor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol particles; stratocumulus; mixed-phase clouds; cloud microphysics; cloud radiative effects; Arctic; Arctic amplification; LES; aerosolpartiklar; stratusmoln; underkylda vattendroppar och iskristaller; molnmikrofysik; molnstrålningseffekter; Arktis; ”large-eddy simulation”; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Clouds have a large impact on Earth’s radiative budget by reflecting, absorbing and re-emitting radiation. They thus play a critical role in the climate system. Nevertheless, cloud radiative effects in a changing climate are highly uncertain. READ MORE

  5. 3. Modelling the effects of organic aerosol phase partitioning processes on cloud formation

    Author : Samuel Joseph Lowe; Ilona Riipinen; Daniel Partridge; Harri Kokkola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud droplet activation; organic aerosol; cloud parcel modelling; Köhler theory; Sensitivity and Uncertainty analysis; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Atmospheric aerosols particles may act as cloud condensation nuclei (CCN) that provide sites for condensation of water vapour for the formation of cloud droplets, called cloud droplet activation. Whether aerosol particles are CCN is determined by their size, composition and the ambient humidity. READ MORE

  6. 4. Arctic clouds - interactions with radiation and thermodynamic structure

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

    Abstract : 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. READ MORE

  7. 5. Historical anthropogenic radiative forcing of changes in biogenic secondary organic aerosol

    Author : Juan Camilo Acosta Navarro; Ilona Riipinen; Annica Ekman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Human activities have lead to changes in the energy balance of the Earth and the global climate. Changes in atmospheric aerosols are the second largest contributor to climate change after greenhouse gases since 1750 A.D. READ MORE
