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]

Towards an exciting EGU General Assembly with HS (and more)

Alberto Viglione November 2, 2023

The EGU Programme Committee convened in late October to finalize the scientific program for the upcoming General Assembly, GA2024. Their task involved organizing the numerous session proposals, spanning 22 divisions, including Inter- and Transdisciplinary (ITS) sessions, discussing the format of scientific sessions (do expect news for virtual posters and PICOs at GA2024!), the mentoring programme, ...[Read More]

A ‘Ticking Bomb’: Understanding the 2023 Glacial Lake Outburst Flood (GLOF) in Sikkim Himalaya

Remya S N & Vishnu Nandan November 2, 2023

Two photos of a glacial lake, on the left in 2022 and on the right in 2013, visually smaller.

In this week’s blog post, Dr. Remya S N and Dr. Vishnu Nandan talk about how optical and radar satellite images were used to characterize the very recent catastrophic Glacial Lake Outburst Flood (GLOF) from the South Lhonak Lake in the Indian Himalaya before and after the flooding and highlight the importance of timely observations and monitoring for people’s livelihoods. The South Lhonak L ...[Read More]

Slow Evolution of Europa’s Interior

Kevin Trinh and edited by Prachi Kar November 1, 2023

“Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth.” This week in News & Views, Kevin Trinh, a PhD student at Arizona State University, discusses how his recent works on Jupiter’s moon Europa can enlighten us about the evolution of Europa’s interior. One of the most promising p ...[Read More]

Geodetic reference frames – Why do we need them?

Detlef Angermann, Laura Sánchez, Martin Sehnal and edited by Rebekka Steffen October 30, 2023

A geodetic reference frame provides the foundation for determining positions on Earth and in space, as well as for reliably quantifying our planet’s changes due to geodynamic processes and ongoing climate change. The ITRF ensures a uniform basis to tackle current and future challenges, including a wide range of location-based applications (navigation, traffic and fleet management, transport ...[Read More]

Training of Trainers to improve Geological Disasters Resilience in Malaysia

Navakanesh M Batmanathan October 30, 2023

Over the years, we have witnessed a growing number of geological disasters due to climatic shifts. One such disaster is the landslide, and the main culprit of such occurrences can be attributed to intense rainfall coupled with high slope angles, especially in areas previously not expected to be susceptible. In this post we share a successful experience of ‘training of trainers’ in Mala ...[Read More]

Recipe to quantify calibration errors in a time-dependent ice sheet model

Beatriz Recinos, Dan Goldberg and James Maddison October 27, 2023

Ice sheet models are awesome tools that help us learn and predict the fate of ice sheets under human-induced climate change. However, all models have errors. What types of uncertainties exist in an ice sheet model and how can we quantify some of them efficiently? Check out our recipe to quantify one type of uncertainty in sea level rise projections: The model calibration error. Not a numerical mod ...[Read More]
