  2. 1. Chemical composition of summertime High Arctic aerosols

    Author : Karolina Siegel; Claudia Mohr; Annica Ekman; Ilona Riipinen; Lise Lotte Sørensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol; chemical composition; Arctic climate; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This thesis presents new insights into the chemical composition of semi-volatile compounds in aerosol samples collected in the central Arctic Ocean close to the North Pole in September 2018. The central Arctic Ocean is an inaccessible location due to the lack of land areas along with heavy pack ice conditions. 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. 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

  6. 4. 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
