Volcanoes release gaseous and particulate into the atmosphere during both eruptive and quiescent activity. Volcanic degassing exerts a dominant role in forcing the nature of volcanic unrest and the timing and style of eruptions. Emissions range from silent exhalation through soils to astonishing eruptive clouds injecting gas and particles into the atmosphere. Strong explosive eruptions are a major natural driver of climate variability potentially impacting on the Earth’s radiation budget over a range of temporal and spatial scales. Persistent quiescent passive degassing and smaller-magnitude eruptions, on the other hand, may impact on regional climate system. Through direct exposure and indirect effects, volcanic emissions may influence local-to-regional air quality and seriously affect the biosphere and environment and, in turn, livelihoods causing socio-economic challenges. Gas emissions are observed and monitored via a range of in situ direct and remote sensing techniques to gain insights into both the subterranean-surface processes and quantify the extent of their impacts. Inverted data are then used to tune models of subsurface and atmospheric/climatic processes as well as laboratory experiments and, finally, to validate and interpret satellite observations. This session focuses on the state-of-the-art and interdisciplinary science concerning all aspects of volcanic degassing and impacts of relevance to the Volcanology, Environmental, Atmospheric and Climate Sciences - including regional climate - and Hazard assessment. We invite contributions on all aspects of volcanic plumes science, their observation, modelling and impacts. We welcome contributions that address hazard assessment and impacts from volcanic degassing both in crises and at persistently degassing volcanoes.
