2. Measuring degradation in cable insulation material under realistic operation conditions
Abstract : One of the challenges in laboratory investigation of degradation and ageing of HVDC cable insulation is related to securing, or in other words, imitating the real service environment of the material specimens. So far, the published data refer to experiments conducted in thermo-oxidative conditions, which is not the case during normal cable operation. READ MORE

3. Aerosol Exchange between Forests and the Atmosphere : Fluxes over a Tropical and a Boreal Forest
Abstract : The main goal of this thesis was to investigate primary biogenic aerosol emission from the Amazon rain forest through measurements of vertical turbulent aerosol number fluxes. In addition, the particle dry deposition sink has been analysed and quantified, and is also compared with the dry deposition sink at a boreal forest site. READ MORE

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

5. 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.
