Clouds in different layers in the Arctic. The high clouds on the horizon are coming from far away, and means a shift in the weather, while low clouds are those that will be studied in the project. Picture taken during a previous project, ASCOS, with a camera attached under a tethered balloon.

A new way to measure makes a better climate model

Professor Michael Tjernström, Department of Meteorology and Bolin Centre for Climate Research, got 29.2 million kronor for his project “Arctic Climate across Scales.”

“We don’t know currently which processes are causing rapid climate change in the Arctic. The estimates of the Arctic’s future climate are uncertain even with today’s best climate models,” says Michael Tjernström.

Equipping the Swedish icebreaker Oden with an automated atmospheric observatory is just one part. The project focuses on three main areas of the Arctic climate: the impact of large-scale weather events in the atmosphere, how clouds form in the Arctic, and finally the energy exchange among the sea, ice, and atmosphere. The new knowledge of these processes in the Arctic will be used to improve current climate models in order to better answer future climate questions.
