1. 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

2. 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

3. Submicrometre aerosol emissions from sea spray and road traffic
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. Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources
Abstract : Emissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. READ MORE

5. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine
Abstract : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. READ MORE
