Division on Atmospheric Sciences

President: Philip Stier (Emailas@egu.eu)
Deputy President: Athanasios Nenes (Email)
ECS Representative: Robert Maiwald (Emailecs-as@egu.eu)

The Atmospheric Sciences (AS) Division is one of the largest divisions of the European Geosciences Union. The research areas covered by the division extend from the large-scale dynamical/meteorological processes and systems in the atmosphere (like cyclones and global atmosphere circulation) to the small scale turbulent mixing, they cover the time frame from centuries (in connection with climate research) to seconds (in the context of fast chemistry). Atmospheric sciences include studies of the atmosphere composition, aerosol and cloud physics, gas-particles interactions and chemical reaction kinetics studied in the labs.

“You Can’t Get Around Clouds”: A Conversation with Climate Scientist Ulrike Lohmann

Prof. Dr. Ulrike Lohmann is a leading atmospheric physicist and climate scientist at ETH Zurich’s Institute for Atmospheric and Climate Science, renowned for her pioneering work on clouds, aerosols, and their interactions within the Earth’s climate system. Her research has significantly advanced our understanding of how microscopic particles influence cloud formation and, in turn, the global energy balance—a critical factor in climate modeling and prediction. This year, Prof. Lohmann was honored with the prestigious Vilhelm Bjerknes Medal from the European …

Current issue of the EGU newsletter

In our October Issue we are feeling the spooky season as we talk with Elizabeth Case, a 'hauntologist' who studies the ghosts of glaciers, Asmae Ourkiya investigates a recent study of the shadows left behind on the climate from a massive eruption in Indonesia, we hear from Peter Alexander, who shares his experience of doing research in an autocratic regime in the Global South, we share all the upcoming webinars planned for November (there are a lot!), and don't miss our announcement of a new Emergency Support policy, to help researchers in the Earth, planetary and space sciences who have been affected by disaster, crisis or conflict.

All this and much more, in this month's Loupe!
