Interactive comment on “Horizontal and vertical structure of reactive bromine events probed by bromine monoxide MAX-DOAS spectroscopy” by
In this study, Simpson et al. analyze the spatial and temporal evolution of BrO column densities in the lower troposphere and their vertical profiles as well as the aerosol optical depths and extinction profiles retrieved from three MAX-DOAS instruments deployed at and around Barrow (Utqiagvik) from early March to mid April 2012 during the BROMEX campaign. The analysis is complemented by the 25...
متن کاملGlobal atmospheric model for mercury including oxidation by bromine atoms
Global models of atmospheric mercury generally assume that gas-phase OH and ozone are the main oxidants converting Hg0 to HgII and thus driving mercury deposition to ecosystems. However, thermodynamic considerations argue against the importance of these reactions. We demonstrate here the viability of atomic bromine (Br) as an alternative Hg0 oxidant. We conduct a global 3-D simulation with the ...

متن کاملAtmospheric reactive chlorine and bromine at the Great Salt Lake, Utah
[1] The presence of chlorine radical species in the lower troposphere has been postulated, but only indirect evidence of its existence has been reported.We present the first direct spectroscopic observations of up to 15 ± 2 pmoles/mole-air chlorine oxide (ClO) in the mid-latitude boundary layer and confirm a previous discovery of the existence of bromine oxide (up to 6 ± 0.4 pmoles/mole-air BrO...
