Manuscript on Tropospheric Halogen Chemistry Published: A manuscript entitled "Active and Widespread Halogen Chemistry in the Tropical and Subtropical Free Troposphere" by Wang, S-Y., J.A. Schmidt, S. Baidar, S. Coburn, B. Dix, T.K. Koenig, E.C. Apel, D. Bowdalo, T.L. Campos, E. Eloranta, M.J. Evans, J.P. diGangii, M.A. Zondlo, R-S. Gao, J.A. Haggerty, S.R. Hall, R.S. Hornbrook, D.J. Jacob, B. Morley, R.B. Pierce, M. Reeves, P.A. Romashkin, A. ter Schure, and R. Volkamer was published in the Proceedings of the National Academy of Sciences(PNAS, doi: 10.1073/pnas.1505142112) on June 29, 2015. The manuscript discusses Tropical Ocean tRoposphere Exchange of Reactive halogen species and Oxygenated VOC (TORERO) airborne measurements which show that tropospheric halogen chemistry has a larger capacity to destroy O3 and oxidize atmospheric mercury than previously recognized. Halogen chemistry is effective at removing O3 at altitudes where intercontinental O3 transport occurs. Public health concerns arise from bioaccumulation of the neurotoxin mercury in fish. Results emphasize that bromine chemistry in the free troposphere oxidizes mercury at a faster rate, and makes water-soluble mercury available for scavenging by thunderstorms(R.B. Pierce, E/RA2, 608-890-1892, brad.pierce@noaa.gov)
