Volcanic eruptions can perturb the atmosphere and climate across a wide range of spatial and temporal scales. The stratospheric injection of sulfur dioxide and the subsequent formation and transport of sulfate aerosols can affect the Earth’s radiative balance, atmospheric circulation, and the coupled atmosphere-ocean system. This constitutes a complex scenario that continues to present important open questions, calling for advanced modeling, computational, and observational approaches.
This session focuses on strategies that combine physical and data-driven modeling, multi-source data, and real-time monitoring to enhance our ability to detect, quantify, model and predict the climate impacts of volcanic activity. We therefore welcome contributions addressing volcano-climate interactions from a broad range of perspectives, including physical modeling, satellite observations, in situ measurements, and paleo records. Particular emphasis is placed on approaches aimed at quantifying short- and long-term effects, identifying eruption-induced anomalies and patterns, and exploiting advanced technologies, including machine learning and emerging computational methods. Case studies of recent or historical major eruptions are also encouraged.
