6. Investigating aerosol effects on stratocumulus clouds through large-eddy simulation
Sammanfattning : Clouds have a large impact on Earth’s radiative budget by reflecting, absorbing and re-emitting radiation. They thus play a critical role in the climate system. Nevertheless, cloud radiative effects in a changing climate are highly uncertain. LÄS MER
7. The influence of biogenic organic compounds on cloud formation
Sammanfattning : Aerosols and clouds provide the largest uncertainty in the atmospheric radiation budget. The main focus of this thesis was to investigate the ability of organic compounds in aerosol particles to form clouds, and more specifically those emitted by living organisms. LÄS MER
8. Chemical perspectives on aerosol-cloud interactions in the High Arctic
Sammanfattning : Atmospheric aerosol particles have important yet highly uncertain impacts on the Earth’s climate, with the largest uncertainties residing in the interactions between aerosols and clouds. The extent to which aerosols act as cloud condensation nuclei (CCN) depends on the chemical composition and size of the particles. LÄS MER
9. Chemical composition of Arctic aerosols and their link to clouds
Sammanfattning : The Arctic is a place particularly vulnerable to climate change, warming at an accelerated rate compared to the rest of the Earth. In this remote environment, the atmosphere, the ocean, the ice, and the land are all interlinked and are shaping a very complex system. LÄS MER
10. Investigating parameters governing liquid-phase cloud activation of atmospheric particles
Sammanfattning : Aerosol-cloud interactions are one of the main sources of uncertainties in modeling and predicting the Earth’s climate. To overcome this uncertainty, we need to improve the understanding about the processes and parameters defining how aerosol particles turn into cloud condensation nuclei (CCN) or ice nuclei (IN) to produce cloud droplets or ice crystals.
