1. The Arctic Atmosphere : Interactions between clouds, boundary-layer turbulence and large-scale circulation
Sammanfattning : Arctic climate is changing fast, but weather forecast and climate models have serious deficiencies in representing the Arctic atmosphere, because of the special conditions that occur in this region. The cold ice surface and the advection of warm air aloft from the south result in a semi-continuous presence of a temperature inversion, known as the “Arctic inversion”, which is governed by interacting large-scale and local processes, such as surface fluxes and cloud formation.

2. Tomographic views of the middle atmosphere from a satellite platform
Sammanfattning : The middle atmosphere is a very important part of the Earth system. Until recently, we did not realize the importance of the structure of this vaporous shell and of the fundamental role it plays in both creating and sustaining life on the planet. LÄS MER
3. Persistent organic pollutants in the atmosphere - spatial and temporal variations
Sammanfattning : In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region. LÄS MER
4. Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation
Sammanfattning : Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the energy balance of the planet. LÄS MER
