  1. 1. Aerosol impacts on subtropical low-level clouds: a satellite and modelling perspective

    Författare :Alejandro Baró Pérez; Annica M.L. Ekman; Frida A.-M. Bender; Abhay Devasthale; Jens Redemann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aerosol-cloud-radiation interactions; cloud microphysics; biomass burning; stratocumulus to cumulus transition; cloud radiative effect; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Complex interactions between aerosols, clouds, and radiation impact Earth's climate. However, several aspects of these interactions remain uncertain, which has led to extensive research over the last decades. LÄS MER

  2. 2. The atmospheric sulfur cycle and its impact on the European climate : a model study

  3. 3. 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.

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

    Författare :Juan Camilo Acosta Navarro; Ilona Riipinen; Annica M.L. Ekman; Hans-Christen Hansson; Risto Makkonen; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Transport and chemical processing of trace gases in deep convective clouds

    Författare :Roman Bardakov; Annica M. L. Ekman; Mary C. Barth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas transport; atmospheric chemistry; convective cloud; box model; new particle formation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Deep convective clouds can efficiently transport trace gases from the planetary boundary layer to the upper troposphere. Once there, some gases will contribute to new particle formation and growth, eventually producing aerosols that are large enough to influence cloud properties, the radiative budget of the Earth, and climate.
