🎉 Congratulations to Carlos Castillo-Rivera on receiving the EGU 2025 Outstanding Student Paper Presentation (OSPP) Award in the Solar-Terrestrial Sciences Division! 👏📣

In this interview, Carlos talks about the research behind his award-winning poster, which explores how the Earth's ionosphere responds differently in the Northern and Southern Hemispheres during geomagnetic storms. He also reflects on his experience at the EGU General Assembly and shares helpful advice for students and early-career researchers preparing to present their own work.

Congratulations on receiving the OSPP Award 2025! What was your reaction when you found out you had been selected for the award? I was very surprised when I received the email, and I read it several times to make sure it was real. After that, I felt extremely proud of my work because I could see the...

The journey to my first EGU General Assembly (GA) 2026 (EGU26) was memorable even before the conference began. What should have been a straightforward train ride to Vienna turned into an unexpected adventure when we were asked to get off at a small station and wait several hours for alternative tran...

Don't miss the spring campfire organized by the EGU-ST Early Career Scientists (ECS) Team, and register now!

In academia, the relationship built between colleagues, support and guidance received from mentors are important factors affecting our success as individuals and as a community. Mentoring influences how we grow and find our way in academia, while shaping our community and institutions by spreading and sharing the culture.

In this campfire, Dr. Manuela Temmer will share her experiences of mentoring in academia. Following her talk, there will be a Q&A session, and the event will end with a networking session where you can benefit from meeting with your colleagues before the EGU GA and share your perspectives with them.

In academia, success is often measured with quantifiable outputs such as publications, grants, and awards. On the other hand, the challenging road leading to this success is not something discussed openly. The relationship we build with our colleagues, the support and guidance we receive from mentor...

🌍🛰️✨ New research on global inductive magnetosphere-ionosphere-thermosphere coupling has been published as a highlight article in Annales Geophysicae.

The study introduces a new global 2D ionospheric model that moves beyond the traditional electric-circuit framework by treating the magnetic field B as a primary variable and explicitly including induction. This enables the model to capture the dynamic evolution of the ionosphere as it interacts with the magnetosphere and thermosphere.

🌍🛰️✨ New research on the effects of geomagnetic mirror force and pitch angles of precipitating electrons has been published as a highlight article in Annales Geophysicae.

The study investigates how the geomagnetic mirror force influences electron density enhancements in the polar atmosphere during energetic electron precipitation. A comparison of two simulation methods using ELFIN and EISCAT observations reveals that including the mirror force reduces estimated electron densities by 40–50% around 80 km altitude, resulting in significantly improved agreement with radar measurements.
