Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion
Journal Article
Overview
abstract
Abstract; ; Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and mitigating space weather impacts. To assess recent achievements, identify scientific priorities, and foster collaboration, a round‐table discussion was hosted by the “; System Understanding of Radiation Belt Particle Dynamics through Multi‐Spacecraft and Ground‐Based Observations and Modeling; ” focus group at the 2024 Geospace Environmental Modeling Workshop. Bringing together around 60 participants, including many students and early‐career scientists (<10 years post Ph.D.), this session explored recent advances, critical open questions, and future directions in radiation belt science and exploration. Participants highlighted significant progress in observations, modeling, and understanding of radiation belt dynamics over the past decade. However, critical challenges remain, including the accurate quantification of source and loss processes, the role of small‐ and meso‐scale processes in radiation belt dynamics, system coupling within the magnetosphere, and the applicability of current knowledge to more active solar and geomagnetic conditions. The critical need for improved observational and modeling capabilities, open science practices, and stronger community collaboration are identified as priorities to drive future advances in radiation belt sciences.;
