Division on Atmospheric Sciences

President: Philip Stier (Emailas@egu.eu)
Deputy President: Andrea Pozzer (Email)
ECS Representative: Mozhgan Amiramjadi (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.

Highlights from EGUsphere

Drawing inspiration from new research shared by EGU scientists, this column brings you some of the latest publications. This edition covers the globe, from the air we breathe in Ireland and China to the waves that stitch the tropics to the Southern Hemisphere. Surface ozone in Ireland: where does it really come from? Ozone plays […]


The Breath of Forests, Cities, and Everything in Between: Eva Pfannerstill and the Air We Cannot See

There is a slow-moving silver shape drifting over the forests and cities of North Rhine-Westphalia. From the ground, it looks almost ceremonial — a Zeppelin NT gliding through the air as though time had reversed by a century. Inside, sensors are humming. And Eva Pfannerstill is watching the data appear. She is not there to admire the view, though the Rhine-Ruhr region from the air is something. She is there because a Zeppelin, of all things, happens to be one …


Methane in India: Why precise measurements and cutting-edge technology matter for climate action

The looming El Niño is likely to hit hard this year, bringing bracing moments to the already warming world. Extreme weather events are no longer just anomalies; they have become far too common in this new reality. It’s clear that our environment is under unprecedented stress. Experts warn of the costs of inaction: between 1995 and 2024, nearly one million lives have been lost due to climate-related disasters globally, with direct economic damages soaring to nearly 4 trillion Euros. Consequently, …


Are we valuing poster sessions enough?

Do not get me wrong, EGUs General Assembly is a great conference and it’s a real pleasure to explore all the science on display, reconnect with colleagues from other institutes, cities and disciplines. But, wandering the venue and seeing all the empty poster walls left a sad feeling. It’s not only singular gaps in an otherwise packed hall, it’s whole empty corridors and not only Monday morning or Friday afternoon. One might ask themselves, if that’s a symptom of how …

Current issue of the EGU newsletter

In our September issue, we ask whether our accelerating technological advancement is still serving science (and scientists), and hear from the incoming Early Career Scientist rep for the Geosciences Instrumentation and Data Systems (GI) Division Luigi Bianco. Don't miss your chance to register for one of our autumn workshops the Outreach Committee is seeking a consultant to help develop a mentoring programme.

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