1. The atmospheric sulfur cycle and its impact on the European climate : a model study
Sammanfattning : .... LÄS MER
2. Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change
Sammanfattning : Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions across the globe. LÄS MER
3. Transport and chemical processing of trace gases in deep convective clouds
Sammanfattning : Deep convective clouds can efficiently transport trace gases from the planetary boundary layer to the upper troposphere. Once there, some gases will contribute to new particle formation and growth, eventually producing aerosols that are large enough to influence cloud properties, the radiative budget of the Earth, and climate.

4. Aerosol impacts on subtropical low-level clouds: a satellite and modelling perspective
Sammanfattning : Complex interactions between aerosols, clouds, and radiation impact Earth's climate. However, several aspects of these interactions remain uncertain, which has led to extensive research over the last decades. LÄS MER
5. Transport of mineral dust into the Arctic : Evaluation of two reanalysis datasets of atmospheric composition
Sammanfattning : The main purpose of this thesis is to examine the mineral dust aerosol transport into the Arctic. Two three-dimensional reanalysis datasets of atmospheric composition, the Copernicus Atmosphere Monitoring Service reanalysis (CAMSRA) and the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are analyzed with regard to dust transport into the Arctic.
