  2. 1. Submicrometre aerosol emissions from sea spray and road traffic

    Author : Monica Mårtensson; Douglas Nilsson; Christer Johansson; Michael Smith; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eddy covariance method; aerosol emissions; submicrometre sea salt parameterisation; primary marine organic aerosols; sea spray; road traffic emission factors; air-sea exchange; aerosol dynamics model; internal aerosol mixing; combustion aerosols; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Abstract : The uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.

  4. 2. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling

    Author : Henrik Grythe; Johan Ström; Krejci Radovan; Bo Gustafsson; Lars Ahlm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine aerosol; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Sea spray aerosols (SSA) are an important part of the climate system through their effects on the global radiative budget, both directly as scatterers and absorbers of solar and terrestrial radiation, and indirectly as cloud condensation nuclei (CCN) influencing cloud formation, lifetime and precipitation. In terms of their global mass, SSA is the largest source and has the largest uncertainty of all aerosols. READ MORE

  5. 3. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

    Author : Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

    Abstract : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. READ MORE

  6. 4. Primary Marine Aerosol Production : Studies using bubble-bursting experiments

    Author : Kim Hultin; Douglas Nilsson; Radovan Krejci; Ian Cousins; Åke Hagström; Erik Swietlicki; Stockholms universitet; []
    Keywords : sea spray; water temperature; dissolved oxygen; photosynthesis; bacterial emissions; V-TDMA; mixing state; eddy covariance; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aerosol particles affect the Earth’s climate, although their impact is associated with large uncertainties. Primary marine aerosol represents a significant fraction of the global aerosol budget considering the Earth’s 70-percentage coverage by oceans. READ MORE

  7. 5. Transport of perfluoroalkyl acids from the ocean to the atmosphere via sea spray aerosol

    Author : Bo Sha; Ian Cousins; Matthew Salter; Jana Johansson; Jonathan P. Benskin; Cora Young; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfluoroalkyl acids; PFAAs; Per- and polyfluoroalkyl substances; PFAS; atmospheric transport; sea spray aerosol; industrial sources; Environmental Sciences; miljövetenskap;

    Abstract : Perfluoroalkyl acids (PFAAs) are a subgroup of per- and polyfluoroalkyl substances (PFAS) that have been widely used in commercial and industrial applications. PFAAs are very persistent in the environment and some can bioaccumulate and have adverse health effects on human health. READ MORE
