1. Quantification of sources and removal mechanisms of atmospheric aerosol particles
Abstract : The focus of this work has been to quantify important processes for climatically relevant aerosols, and to improve our understanding of, and ability to accurately model, aerosols in the atmosphere on a large scale. This thesis contains five papers focused on different parts of the life cycle of atmospheric aerosol particles. READ MORE

2. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
Abstract : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. READ MORE

3. Traffic Emissions of Aerosols
Abstract : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. READ MORE

4. Primary Marine Aerosol : Validation of sea spray source functions using observations and transport modeling
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. Development and application of Differential Optical Absorption Spectroscopy (DOAS) for Asian urban air monitoring and atmospheric research
Abstract : Urban air pollution is a serious concern in developing countries and there is a need for qualified measurements of a range of compounds on a nation-wide basis. A suitable potential technique for air monitoring is Differential Optical Absorption Spectroscopy (DOAS). READ MORE
