About
Emmanuel Tison is a leading geochemist whose research bridges volcanology, atmospheric chemistry, and climate science. His work focuses on the environmental impacts of volcanic emissions, particularly the transformation and transport of sulfur species in the troposphere. His most cited paper, "Large-scale particulate air pollution and chemical fingerprint of volcanic sulfate aerosols from the 2014–2015 Holuhraun flood lava eruption of Bárðarbunga volcano (Iceland)" (2019, 29 citations), provides critical insights into the poorly constrained oxidation rates of sulfur dioxide (SO₂) to sulfate aerosols (SO₄²⁻) in volcanic plumes. By characterizing the chemical fingerprint of these aerosols, Tison’s research has advanced our understanding of how large-scale effusive eruptions can significantly degrade regional air quality and influence climate. This work is particularly notable for its direct measurement of sulfate formation in a tropospheric volcanic plume—a process often modeled but rarely observed. Tison’s contributions are essential for improving volcanic hazard assessments and refining global climate models, making him a key voice in the study of Earth’s natural aerosol cycles.
