  4. 8. Insights into key processes governing atmospheric aerosol loadings and their interactions with clouds

    Författare :Emelie Linnéa Graham; Ilona Riipinen; Claudia Mohr; Paul Zieger; Annica M. L. Ekman; Marianne Glasius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosol particles are ubiquitous in the atmosphere and an essential part of the atmospheric radiation balance regulating the Earth’s temperature. Aerosol-cloud interaction still remains the largest single uncertainty in future climate projections. In addition, aerosols are also responsible for air pollution, causing severe health effects.
