Dear Colleagues,

We are pleased to announce that we are accepting abstract submissions for our AGU25 session: SH009 : From Initiation to Impact: Understanding CMEs as Drivers of Space Weather

Understanding the life cycle of CMEs—from their initiation at the Sun, their propagation through the heliosphere, to their geoeffective consequences at Earth—is essential for accurate space weather forecasting and mitigation strategies. Observations from multiple vantage points, such as those from PSP, SolO, STEREO, SOHO, Aditya L1, the recent PUNCH mission and the upcoming ESA Vigil mission, along with ground-based radio observatories, enable three-dimensional reconstruction of CME morphology, kinematics, and their interaction with the ambient solar wind. Advances in numerical magnetohydrodynamic (MHD) simulations and the incorporation of AI/ML techniques into these models are revolutionising space weather prediction. This session invites contributions that aim to comprehensively investigate CME evolution using a synergistic approach that combines multi-wavelength and multi-vantage point observations, numerical modelling, and AI/ML-based methodologies. A special focus is given to CME-CME interactions, which can lead to complex ejecta with enhanced geoeffective signatures, often resulting in more intense geomagnetic storms than individual events (e.g., May and October 2024 storms). We welcome contributions from researchers at all career stages, especially early-career scientists and students.

As we believe in fostering collaboration and promoting diverse perspectives, we welcome submissions from researchers at all career stages, including early-career scientists and students.

The abstract submission deadline is Wednesday, 30 July, 2025, 23:59 EDT/03:59 UTC. Please forward this to your colleagues who may be interested in our session.

Anshu, on behalf of,
