  2. 1. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change

    Author : Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; Air quality; Land use; General circulation; Atmosphere-Ocean interactions; Aerosol climate effects; Earth system modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. READ MORE

  4. 2. 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

  5. 3. 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

  6. 4. Lifecycle of Black Carbon in the Arctic

    Author : Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Abstract : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. READ MORE

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

    Author : Maryam Dalirian; Ilona Riipinen; Ottmar Möhler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CCN activation; surface tension; coated aerosols; black carbon; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : 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.
