Geochemical Controls on the Ice Nucleating Efficiency of Volcanic Ash
Volcanic ash particles from explosive eruptions are increasingly recognised to be capable of acting as ice nuclei, but factors determining the ash ice nucleating efficiency have yet to be elucidated. An experimental approach uniquely bridging volcanic geochemistry and atmospheric science will be applied to establish the link, if any, between ash ice nucleating efficiency and the various physicochemical processes and properties that define ash. Experimental data will ultimately be parameterised for use in model simulations to predict regional ice nuclei concentrations based on various eruption scenarios.
This Marie Skłodowska-Curie Fellowship project, funded by the European Commission's Horizon 2020 Research and Innovation Programme, will contribute to a greater understanding of the potential impacts of ash emissions from explosive eruptions on the atmosphere and on climate.
Project duration: 2 years (01/2018 - 01/2020)
