  2. 2. 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

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

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

    Abstract : 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.

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

    Author : Alejandro Baró Pérez; Annica M.L. Ekman; Frida A.-M. Bender; Abhay Devasthale; Jens Redemann; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Transport of mineral dust into the Arctic : Evaluation of two reanalysis datasets of atmospheric composition

    Author : Sebastian Böö; Annica M. L. Ekman; Adam Kristensson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arktis; transport; damm; återanalys; reanalys; aerosol; meteorologi; Meteorology;

    Abstract : The main purpose of this thesis is to examine the mineral dust aerosol transport into the Arctic. Two three-dimensional reanalysis datasets of atmospheric composition, the Copernicus Atmosphere Monitoring Service reanalysis (CAMSRA) and the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are analyzed with regard to dust transport into the Arctic.
