  1. 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

  2. 2. 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 : NATURAL SCIENCES; NATURVETENSKAP; 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

  3. 3. Arctic clouds - interactions with radiation and thermodynamic structure

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

    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

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

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

  5. 5. Volcanic Aerosols in the Upper Troposphere and Stratosphere – Aircraft- and Satellite-Based Observations

    Author : Sandra Andersson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbonaceous aerosol; sulphate; ash; volcanic particles; upper troposphere; lowermost stratosphere; Stratospheric aerosol; volcanism; aerosol optical depth; radiative forcing; Fysicumarkivet A:2015:Andersson;

    Abstract : Volcanic eruptions are the largest source of variability in the stratospheric particle concentration as they inject SO2 that is subsequently converted into sulphate particles. No major perturbation of the stratospheric aerosol load has been observed since the large eruption of Pinatubo in 1991, but several moderate eruptions after 2000 have caused deviations from stratospheric background conditions.
