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.

CLOUDLAB: Cloud research in a natural laboratory
It’s murky grey, windy, and freezing when we head out into the countryside of the Swiss pre-Alps. We are looking for low hanging clouds to serve as our natural laboratory. Wintertime low stratus clouds can cover Switzerland for days. This type of cloud is stable with temperatures below 0 ºC and it contains plenty of liquid cloud droplets, but no ice crystals. These are the perfect background conditions for starting our experiments (see Figure 1, left). We launch an uncrewed …

China’s Hainan Unlocks Mysteries of Heat and Sodium Transport 80–100 km Above Earth
When we gaze at the sky, our eyes often linger on blue horizons, floating clouds, or twinkling stars—rarely do we think about the critical processes unfolding 80 to 100 km above ground. This region, known as the mesopause, acts as a vital transition zone for aviation and aerospace activities (not vital for routine commercial aviation, but it is indispensable for high-altitude aerospace, experimental aviation, spacecraft re-entry/launch, and the broader atmospheric models that underpin all aviation operations), where subtle changes in …

Why “Perfect” Infrared Spectrometers Are a Myth – and Why That Matters for Atmospheric Measurements
Modern atmospheric science relies on precise and stable measurements to understand how the composition of the atmosphere evolves over time. From air quality to climate-relevant trace gases, long-term observations are essential for identifying trends and detecting subtle changes. One of the key tools enabling such measurements is infrared spectroscopy, which allows scientists to identify and quantify atmospheric gases by measuring how molecules absorb infrared radiation from the Sun. High-resolution Fourier Transform Infrared (FTIR) spectrometers are widely deployed at ground-based monitoring …

Building a library of observed air mass trajectories to study aerosol-cloud interactions
Marine low clouds, such as stratocumulus, play a central role in regulating Earth’s climate by reflecting incoming sunlight back to space. Yet these clouds are notoriously difficult to simulate and predict. One reason is that their evolution depends strongly on the surrounding atmosphere: temperature structure, moisture, winds, and aerosols all interact in complex ways. As a result, cloud responses seen in one situation may not apply to another. A common challenge in the study of clouds is that observations often …

Current issue of the EGU newsletter
In our March issue, we are preparing for the annual General Assembly on the EGU blogs and with a special webinar to help all EGU26 attendees refresh their knowledge of the meeting we are all systems go here in EGU HQ! Also learn about what it's like to spend 25 years working with Interactive Open Access publishing, don't miss out on science for policy events at EGU26, and the EGU awards and medals are now open for nominations - the process is probably easier than you think!
All this and much more, in this month's Loupe!
