1. Long range transport through the atmosphere : a study of sulfur as an air pollutant
Sammanfattning : .... LÄS MER
2. Decision processes in discretionary long-range travel
Sammanfattning : The present study is founded in transportation research but is interdisciplinary in that it is drawing on research areas like consumer behaviour, cognitive science, economic psychology and marketing. The results will provide knowledge to 1) researchers, who need a deeper understanding of travel behaviour in order to develop better models, 2) policy makers, who need information on transport demand for planning the infrastructure and for evaluating environmental consequences and 3) marketing analysts, who need information on the whole complex of business and discretionary travel pattems.

3. Polybrominated diphenylethers in the environment - Local and long range transport
Sammanfattning : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. LÄS MER
4. Nonmethane hydrocarbons and nitrogen oxides in background air : long-range transport of precursors in relation to oxidant formation

5. Statistical properties of the atmosphere influencing long-range transport of air pollutants
Sammanfattning : This thesis deals with some statistical properties of the atmosphere of importance for the transport and removal of air pollutants. Clouds and precipitation can strongly influence the behaviour of atmospheric pollutants. Thus, we need to know the frequency of occurrence of cloud and rain events in order to estimate e.g. LÄS MER
