Division on Solar-Terrestrial Sciences

President: Emilia Kilpua (st@egu.eu)
Deputy President: Olga Malandraki (omaland@astro.noa.gr)

The Division on Solar-Terrestrial Sciences (ST) considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth’s magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modelling techniques are used to better our understanding of how our local star defines the neighbourhood that we live in.

Assessing the impact of chlorine ions on solar proton event induced ozone loss

Particle Precipitation High energy particles (e.g. electrons and protons) that precipitate at high latitudes can alter the chemical composition of the atmosphere by different photochemical reactions. This mainly happens due to primary collision processes and subsequent ion and neutral-chemistry reactions. Such reactions ordered by increasing energy are, for example, excitation, photo-dissociation, photo-ionization and dissociative ionization. These particles can come from various sources in outer space, accelerated by different processes to varied energies, and they affect different altitude ranges of the …


ST-ECS Networking Campfire on “Time management strategies for research productivity”

Life in academia can be complex, involving handling multiple roles while developing and sustaining a successful career. Therefore, it can be challenging to balance research responsibilities with other commitments. Understandably, effective time management is essential for researchers to be productive and to achieve their goals, without sacrificing other important matters in life. The Early Career Scientists (ECS) team of the Solar-Terrestrial (ST) division of the European Geophysical Union (EGU) is organizing a campfire event to discuss this matter. In this …


Exploring Magnetosheath Jets and their dependence on Solar Wind structures

Dayside of the Earth’s magnetic field Our understanding of the relationship between Earth’s magnetic field and the particles from the Sun that constantly bombard it, known as the solar wind, has significantly advanced in recent decades. The availability of numerous spacecraft measurements has provided valuable insights into this interaction. The solar wind, composed of high-speed particles carrying the interplanetary magnetic field from the Sun, undergoes a rapid deceleration as it collides with Earth’s magnetic field. This deceleration creates a shockwave, …

Current issue of the EGU newsletter

Scientists find that faster warming in the Arctic will lead to a global 2 degree Celsius rise being reached eight years earlier than if the region was warming at the average global rate. And Geodesy researcher Andreas Kvas explains how Earth’s geometric shape, orientation in space, and gravity field are affected by climate-relevant processes.

This month, EGU observed International Day for Biosphere Reserves, while also diving deep into monster lore to mark 90 years since the first fake photo of the Loch Ness Monster.
