The scientific community still does not fully understand how ice is formed in clouds. The Swedish Research Council has granted researcher Erik Thomson a project grant of 4.3 million SEK to study ice particles in clouds and how their formation is affected by changes in the air quality and the climate.
Clouds consist of water, ice or a mix of the two, and the formation of ice in a cloud requires that certain particles are present. The exact process involved remains poorly understood, but Thomson and his colleagues in Gothenburg are planning on changing this.
Erik Thomson has a PhD from Yale University in USA and is currently in his third year as a postdoc at the Department of Chemistry and Molecular Biology at the University of Gothenburg. The project grant for junior researchers from the Swedish Research Council will enable him to continue studying ice particles in clouds.
‘It’s nice to have one’s work acknowledged at such a high level in the scientific community,’ says Thomson.
IN one of the projects, Thomson and his colleagues at the University of Gothenburg are studying how emissions from ships affect the formation of ice in clouds. The reason for his research is the increasing number of vessels in Arctic and northern waters. The Arctic has a climate that makes the effects of human-made emissions much more noticeable than elsewhere, which could mean that emissions from ships are severely affecting the Arctic climate. Emissions are measured outside the Port of Gothenburg, and the project is a collaboration between the University of Gothenburg, the Swedish Environmental Research Institute, Goethe University Frankfurt and CRAICC (Cryosphere-atmosphere interactions in a changing Arctic climate, which is part of the Nordic Top Research Initiative).
