Volatile emissions from planetary surfaces provide critical insights into the evolution of Solar System bodies. These emissions, involving gases, ices, and dust, can be triggered by natural factors such as solar radiation or impacts, or induced by human activities like drilling. They are observed in diverse environments, from plume eruptions on icy moons like Enceladus and Europa, to jet activity on comets, and subsurface releases on Mars or the Moon. However, the physical mechanisms driving these processes remain poorly understood due to the complex conditions and the interplay of thermal, mechanical, and chemical factors. Modeling plays a crucial role in bridging this knowledge gap.

This focus session aims to highlight how advanced numerical modeling can be used to investigate volatile-related processes across different planetary environments. We welcome contributions focused on modeling of surface, subsurface, and interior processes, atmospheric effects, impact phenomena, and hydrodynamics. The session will provide a platform to share current results, discuss methodological developments, and identify future directions in modeling planetary volatile emissions. By fostering interdisciplinary dialogue, we seek to enhance our understanding of volatile activity and to support the interpretation of data from past, ongoing, and upcoming space missions (e.g., Juice, Rashid, ExoMars, Curiosity).
