Division on Solar-Terrestrial Sciences

President: Emilia Kilpua (Emailst@egu.eu)
Deputy President: Alexis Rouillard (Email)
ECS Representative: Liliana Macotela (Emailecs-st@egu.eu)

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.

AGATA: Advancing Polar Science through Multi-Instrument Integration and Collaboration

Scientific research has long recognized that solar-terrestrial interactions play a crucial role in shaping the polar atmosphere, impacting both climate dynamics and atmospheric coupling across different layers. Understanding these interactions is key to unraveling their far-reaching effects on Earth’s climate, space weather, and global atmospheric processes. The recognition of these critical processes has driven international research initiatives like the International Polar Year (IPY) programs, which involved thousands of researchers and facilitated global collaboration and data sharing. These efforts have established …


Meet Erika Palmerio, the 2024 Outstanding Early Career Scientist Awardee of the Solar-Terrestrial Division!

Congratulations on receiving the EGU 2024 ST Division Outstanding Early Career Scientist Award for your exceptional research in analyzing complex solar transients and their effects on space weather. What does this recognition mean to you personally, and how does it impact your work in this fascinating field? Thank you so much! Receiving an award from EGU is of particular significance to me, since my very first conference as an early PhD student was the EGU General Assembly in 2016. I …


ST-Early Career Scientist team 2024-2025

We are a group of Early Career Scientists (ECSs) from the Solar-Terrestrial (ST) division, dedicated to organizing events and activities for ST-ECSs both during the EGU General Assembly and throughout the year. Our goal is to enhance ECS visibility and create valuable networking opportunities. Currently the team is formed by: Dr. Liliana Macotela, ECS Representative Liliana is a senior researcher at the Norwegian Research Centre in Tromsø, Norway. Her research focuses on Situational Space Awareness, particularly in the areas of …


ST-ECS Networking Campfire: “How to Successfully Apply for Fellowships”

Securing a research fellowship is a major milestone for early-career scientists, providing not only financial support but also access to cutting-edge facilities, valuable collaborations, and opportunities for independent research. However, standing out in the competitive world of research funding requires mastering the art of grant writing and proposal crafting. To help young scientists navigate the fellowship application process, the Early Career Scientists (ECS) team of the Solar-Terrestrial (ST) division of the European Geosciences Union (EGU) is organizing a Campfire Event …
