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.

🌍🛰️✨ New research on a statistical study of the O2 atmospheric band aurora has been published as a highlight article in Annales Geophysicae.

Analysing 378 auroral events, this study finds an average geomagnetic latitude of ~67.7° in both hemispheres and a peak emission altitude near 103 km. Aurora brightness spans from 200 kR to over 5500 kR, with intensity and altitude strongly linked to geomagnetic activity.

🌍🛰️✨ New research on field-aligned currents at auroral latitudes has been published as a highlight article in Annales Geophysicae.

Using high-resolution (50 Hz) magnetic field measurements from ESA’s Swarm A and C satellites, the study investigates field-aligned currents (FACs) at auroral latitudes down to scales below 1 km, a level of detail rarely accessible in spaceborne observations.

Observing a Geomagnetic Superstorm in Action: First Observations With a Sub-L1 Solar Wind Monitor ☀️⚡🛰️🌍

The strongest geomagnetic storm since 2003, triggered by five interacting solar coronal mass ejections (CMEs) ☀️💥, was captured using a sub-L1 solar wind monitor. Researchers tracked the early solar wind structures and the storm’s evolution, revealing complex interactions that drive extreme space weather ☀️🌪️🧲🌍. These insights are vital for improving space weather forecasts and protecting satellites, power grids, and communications ⚡🌐.

How Earth’s Weather Shapes Space Weather: Exploring Their Interplay ☀️🛰️🌍🌪️🌀

The ionosphere–thermosphere is the vital interface where Earth’s atmosphere transitions into space, influenced by continual wave 🌊 activity from terrestrial weather systems in the troposphere and stratosphere, as well as by solar ☀️and magnetic 🧲 forces. Initial results from NASA Living with a Star research reveal that waves and atmospheric processes generated below strongly drive variability in ionosphere–thermosphere structure and composition with impacts larger than previously recognised ⚡🌐. This variability influences space weather prediction and is of national importance for safe operations 🛰️ in very low Earth orbit 🔗

The ionosphere-thermosphere (IT) is a convergence point of energy and processes that interconnect Earth’s atmosphere with space. Processes generated by terrestrial weather in the lower atmosphere (i.e., troposphere and stratosphere, altitudes less than ~ 50 km) are recognized by the scientific...
