  1. 1. Regional studies of the optical, chemical and microphysical properties of atmospheric aerosols Radiative impacts and cloud formation

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Admir Créso Targino; Stockholms universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; particles; optical properties; cloud; ice crystals; chemical composition; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap;

    Sammanfattning : Atmospheric particles are ubiquitous in the Earth’s atmosphere and have potential to influence atmospheric chemistry, visibility, global climate and human health, particularly downwind from major pollution sources. The main objective of this thesis was to investigate questions pertaining to the microphysical, chemical and optical properties of aerosol particles by using in situ data collected during four experiments carried out in different regions of the Northern Hemisphere.

  2. 2. Satellite microwave measurements of ice cloud properties

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Bengt Rydberg; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cirrus; radiative transfer; CIWSIR; microphysical properties; inversions; Odin;

    Sammanfattning : Ice clouds play an important role in Earth's radiation balance and climate because they reflect incoming sunlight and trap outgoing infrared radiation. There is still an uncertainty about how ice clouds will respond to the effects of global warming. Many climate models use prognostic cloud mass schemes to represent cloud feedbacks. LÄS MER

  4. 4. Cloud Studies with the Droplet Aerosol Analyzer

    Detta är en avhandling från Division of Nuclear Physics

    Författare :Maria Berghof; Lunds universitet.; Lund University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cloud; Aerosol; DAA;

    Sammanfattning : Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. LÄS MER

  5. 5. Satellite microwave measurements of cloud ice properties

    Detta är en avhandling från Division of Nuclear Physics

    Författare :Bengt Rydberg; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-mm; cirrus; upper troposphere; Odin; remote sensing; CloudSat; data retrieval;

    Sammanfattning : Upper tropospheric cloud ice and water vapour are two intimately connected components of the atmosphere, that influence the Earth's energy budget. The response of these components to a warming climate is not well understood. LÄS MER
