Journal ArticleDOI
Atmospheric iodine levels influenced by sea surface emissions of inorganic iodine
Lucy J. Carpenter,S. M. MacDonald,Marvin D. Shaw,R. Kumar,R. W. Saunders,Rajendran Parthipan,Julie Wilson,John M. C. Plane +7 more
TL;DR: For example, this article showed that the reaction of ozone with iodide could account for around 75% of observed iodine oxide levels over the tropical Atlantic Ocean, where bromine and iodine-containing compounds substantially reduce regional and possibly global, tropospheric ozone levels.
Journal ArticleDOI
Studies of the Formation and Growth of Aerosol from Molecular Iodine Precursor
R. W. Saunders,R. Kumar,J. C. Gómez Martín,Anoop S. Mahajan,Benjamin J. Murray,John M. C. Plane +5 more
TL;DR: In this paper, the formation and growth of IOPs originating from molecular iodine precursor was studied at room temperature as a function of water vapour, and sulphuric and oxalic acid vapours.
Journal ArticleDOI
Glass formation and unusual hygroscopic growth of iodic acid solution droplets with relevance for iodine mediated particle formation in the marine boundary layer
Benjamin J. Murray,Allen E. Haddrell,S. Peppe,James F. Davies,Jonathan P. Reid,Daniel O'Sullivan,H. C. Price,R. Kumar,R. W. Saunders,John M. C. Plane,Nsikanabasi Silas Umo,T. W. Wilson +11 more
TL;DR: In this paper, the authors explore the response of super-micron sized aqueous iodic acid solution droplets to varying humidity using both Raman microscopy and single particle electrodynamic traps.
Journal ArticleDOI
Insights into the Photochemical Transformation of Iodine in Aqueous Systems: Humic Acid Photosensitized Reduction of Iodate
TL;DR: A model of iodine chemistry in the open ocean tropical boundary layer, which incorporates experimental results, is able to account for the observed enrichment of iodine in marine aerosol.
Journal ArticleDOI
Halogen species record Antarctic sea ice extent over glacial–interglacial periods
Andrea Spolaor,Andrea Spolaor,Paul Vallelonga,John M. C. Plane,Natalie Kehrwald,Jacopo Gabrieli,Cristiano Varin,Clara Turetta,Giulio Cozzi,R. Kumar,Claude F. Boutron,Carlo Barbante +11 more
TL;DR: In this article, the TALDICE (TALos Dome Ice CorE) ice core was used for speciation measurements of bromine and iodine in the last 215 ky.
