  1. 1. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation

    University dissertation from Göteborgs universitet

    Author : Julia Hammes; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOA; VOC; anthropogenic; biogenic; FIGAERO; CIMS; HOMs; ELVOCs; atmospheric oxidation; chemical mechanism; NOx; limonene; a-pinene; TMB; ozone; nitrate; OH; radical chemistry; RO2; G-FROST; GO:PAM;

    Abstract : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

  2. 2. Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties

    University dissertation from Göteborgs universitet

    Author : Anna Lutz; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas to particle conversion; volatility; secondary organic aerosols; FIGAERO; CIMS; monoterpenes; isoprene; SOA; BVOC;

    Abstract : Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the atmosphere are of secondary origin, formed as a result of gas to particle conversion. READ MORE

  3. 3. Physical properties and processes of secondary organic aerosol and its constituents

    University dissertation from Göteborgs universitet

    Author : Kent Salo; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing; VOC; volatility; monoterpenes; atmosphere; VTDMA;

    Abstract : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. READ MORE

  4. 4. Information in use Aspects of information quality in workflows

    University dissertation from Ronneby : Blekinge Institute of Technology

    Author : Patrik Brandt; ; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital services; information; workflow; information quality; SOA;

    Abstract : This thesis is founded on the global growth of the service sector and its significance for society as a whole and for the individual human being. In the last decade, technology has changed the way services are created, developed and delivered in remarkable ways. READ MORE

  5. 5. Black Death - Blue Skies - White Clouds : Water Vapour Uptake of Particles Produced from Traffic Exhaust and their Effect on Climate

    University dissertation from Fysiska institutionen, Lunds universitet

    Author : Cerina Wittbom; [2017-04-25]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCN ACTIVATION; Soot; water vapour; climate; SOA; Traffic emission; Fysicumarkivet A:2017:Wittbom;

    Abstract : Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. READ MORE
