WACL atmospheric chemistry publication a runner up in the European Geosciences Union 2024 Atmospheric Chemistry and Physics Paul Crutzen Award.

“Negligible Temperature Dependence of the Ozone-Iodide Reaction and Implications for Oceanic Emissions of Iodine” was recognised as one of three runners up in the annual ACP Paul Crutzen Publication Award. The award, created in honour of Paul Crutzen, Nobel Prize awardee, recognises an outstanding publication in the journal ACP that advances our understanding of atmospheric chemistry and physics. 

The paper reported laboratory measurements of the kinetics of the heterogeneous reaction between ozone and iodide in environmentally relevant conditions, to address conflicting results in previous kinetic studies. The results of these experiments were used to constrain an ocean-atmosphere coupled chemistry box model to improve understanding of the temperature-dependent emissions of iodine from the ocean.

This work was carried out by recently-graduated PhD student Lucy Brown, supported by the collaborative efforts of Ryan Pound, Lyndsay Ives, Matthew Jones, and Steve Andrews, under the supervision of Professor Lucy Carpenter
