3-3-3-3-3-3-3-3-3-3-3-3-3 From: Giuseppe Salerno <giuseppe.salerno@xxxxxxx> Dear all, Your abstract submissions are very welcome in the interdisciplinary session: 'GMPV10.3 - Volcanic Plumes: Insights into Volcanic Emissions and their Impacts on the Environment, Climate and Health' at the annual EGU congress at Vienna (Austria) between 3 and 8 April 2022. *Deadline abstract submission. 12 January 2022, 13:00 CET* Session Detail ( https://urldefense.com/v3/__https://meetingorganizer.copernicus.org/EGU22/sessionprogramme__;!!IKRxdwAv5BmarQ!NOn4_TnqZxAa6Dl9zgfSWYvn621x-p8a4S6c7wnb2Sefz-jeh-s-0w6zjx_TUEE$ <https://urldefense.com/v3/__https://meetingorganizer.copernicus.org/EGU22/sessionprogramme__;!!IKRxdwAv5BmarQ!NvgzMmBxfKLARFJKHHV7dYb2vD4cOpATY9QkGhQH--lr_IzREkb1kEzdVtxyqZ0$> ) Volcanoes release gas effluents and aerosol particles into the atmosphere during eruptive episodes and by quiescent emissions. Volcanic degassing exerts a dominant role in forcing the timing and nature of volcanic unrest and eruptions. Understanding the exsolution processes of gas species dissolved in magma, and measuring their emissions is crucial to characterise eruptive mechanisms and evaluate the subsequent impacts on the atmospheric composition, the environment and the biosphere. Emissions range from silent exhalation through soils to astonishing eruptive clouds that release gas and particles into the atmosphere, potentially exerting a strong impact on the Earthâ??s radiation budget and climate over a range of temporal and spatial scales. Strong explosive volcanic eruptions are a major natural driver of climate variability at interannual to multidecadal time scales. Quiescent passive degassing and smaller-magnitude eruptions on the other hand can 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. Volcanic gases can also present significant hazards to populations downwind of an eruption, in terms of human, animal and plant health, which subsequently can affect livelihoods and cause socio-economic challenges. Gas emissions are measured and monitored via a range of in-situ and remote sensing techniques, to gain insights into both the subterranean-surface processes and quantify the extent of their impacts. In addition, modelling of the subsurface and atmospheric/climatic processes, as well as laboratory experiments, are fundamental to the interpretation of field-based and 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 issues around the assessment of hazards and impacts from volcanic degassing both in crises and at persistently degassing volcanoes. Looking forward to receiving your abstracts, On behalf of the co-conveners Giuseppe Salerno, Pasqualle Sellitto, Tjarda Roberts, Emily Mason, Amy Donovan 3-3-3-3-3-3-3-3-3-3-3-3-3 ------------------------------
