Can you share what this recognition means to you personally and how it reflects the broader contributions of the scientific community to space weather research? I am deeply honored to receive the Birkeland Medal and grateful to all the colleagues, mentors, and collaborators who have supported my research career ...[Read More]

Impact of upper atmosphere and ionosphere associated with an extremely explosive eruption of the Tonga volcano

authored by Atsuki Shinbori, and edited by Shreedevi P. R. February 5, 2025

1. Introduction Severe natural phenomena of geophysical, hydrological, and meteorological origins cause natural hazards that negatively impact human activity or the environment. Many people living on the earth suffer from natural hazards every year. Although we can predict some natural hazards (e.g., typhoons) in near real-time, forecasts of the geophysical natural hazards such as large earthquake ...[Read More]

Newly released: Aurora Handbook and Field Guide for citizen science studies in view of the upcoming SolarMaX campaign

Maxime Grandin, Katie Herlingshaw, and Bea Gallardo-Lacourt November 11, 2024

Given the recent surge in solar and geomagnetic activity, spectacular auroral displays have been visible down to the mid-latitudes several times since the beginning of 2024. But it is not always so easy to know when to go out, where to look, and how to take good pictures of the aurora. And what if the observations collected by seasoned and first-time aurora chasers could help in advancing the scie ...[Read More]

ST-ECS Networking Campfire – How to convene a scientific session

authored by Liliana Macotela, edited by Eleanna Asvestari October 29, 2024

Convening a session at academic conferences is no doubt time-consuming, but they are also the primary catalysts for establishing a research network and significantly boosting your academic profile. Particularly for Early Career Scientists (ECS), the idea of convening a session can be fearful and many worry that they don’t know how to do it or whether they can wrap up the session smoothly. The ECS ...[Read More]

Meet our divisions ECS team that organized events throughout 2023-2024

Liliana Macotela April 14, 2024

Hi, this is your ST-ECS team 2023-2024. We are a group of Early Career Scientists (ECSs) of the Solar-Terrestrial (ST) division, and we organize events and activities with and for ST-ECS, both during the EGU General Assembly and throughout the year. Our aim is to increase the visibility of ECSs and provide you with opportunities for networking. Dr. Liliana Macotela, ECS Representative Lilia ...[Read More]

Solar-Terrestrial ECS Drinks: preGA Icebreaker Get-together for all ST ECSs before the opening reception. We’re meeting up at 15:00 hours in front of the entrance of the name badges coll ...[Read More]

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

authored by Monali Borthakur, edited by Jia Jia and Eleanna Asvestari November 3, 2023

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-dissoc ...[Read More]

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

authored by Liliana Macotela Cruz, edited by Eleanna Asvestari October 9, 2023

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 ...[Read More]

Exploring Magnetosheath Jets and their dependence on Solar Wind structures

authored by Florian Koller, edited by Eleanna Asvestari June 13, 2023

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 c ...[Read More]

Why faculae “vanish” on active Suns

authored by Nina-Elisabeth Nèmec, edited by Eleanna Asvestari April 23, 2023

The Earth’s primary energy source is the radiative energy flux (i.e., the Total Solar Irradiance, TSI) from the Sun. Understanding the TSI or the solar irradiance output in particular wavelengths is important, as it is crucial for sustaining life of metabolisms on Earth and in answering the question of how life emerged on Earth. It has been shown that magnetic activity on the solar surface is one ...[Read More]
