Session Proposal: Volcanic Eruptions and Climate: Observations, Modeling, and Impacts (AGU25)

V035
Volcanic Eruptions and Climate: Observations, Modeling, and Impacts

Session ID#: 250094

Session Description:
Volcanic activity plays a key role in modulating atmospheric processes at both regional and global scales. Explosive eruptions, persistent degassing, and aerosol emissions can significantly influence climate dynamics, yet their interactions with the coupled atmosphere-ocean system remain only partially understood. This session focuses on forward-looking strategies that combine multi-source data, real-time monitoring, and advanced modeling—including hybrid and data-driven approaches—to enhance our ability to monitor, interpret, and anticipate the climate impacts of volcanic activity. We welcome contributions that merge satellite, in situ, and paleo records with physical models and computational techniques. Emphasis is placed on detecting anomalies, identifying patterns, and quantifying both short- and long-term effects. Case studies of recent or historical major eruptions and the use of innovative analytical or simulation methods are particularly encouraged. The session promotes interdisciplinary dialogue among volcanology, atmospheric sciences, and computational modeling to advance understanding of how volcanic processes influence the climate system.
