Global atmospheric model for mercury including oxidation by bromine atoms
Global atmospheric model mercury oxidation bromine atoms
2010/12/28
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...
Bromine measurements in ozone depleted air over the Arctic Ocean
Bromine measurements ozone depleted air the Arctic Ocean
2010/8/16
In situ measurements of ozone, photochemically active bromine compounds, and other trace gases over the Arctic Ocean in April 2008 are used to examine the chemistry and geographical extent of ozone de...
Modelling chemistry over the Dead Sea: bromine and ozone chemistry
Modelling chemistry Dead Sea bromine ozone chemistry
2009/8/7
Measurements of O3 and BrO concentrations over the Dead Sea indicate that Ozone Depletion Events (ODEs), widely known to happen in polar regions, are also occuring over the Dead Sea due to the very hi...
Estimating the contribution of bromoform to stratospheric bromine and its relation to dehydration in the tropical tropopause layer
bromoform stratospheric bromine dehydration tropical tropopause layer
2009/1/16
The contribution of bromoform to the stratospheric bromine loading is estimated using the one-dimensional tropical mean model of Folkins and Martin (2005), which is constrained by observed mean profil...
First-year sea-ice contact predicts bromine monoxide (BrO) levels at Barrow, Alaska better than potential frost flower contact
sea-ice BrO levels Alaska potential frost

Reactive halogens are responsible for boundary-layer ozone depletion and mercury deposition in Polar Regions during springtime. To investigate the source of reactive halogens in the air arriving at Ba...
Consistent simulation of bromine chemistry from the marine boundary layer to the stratosphere – Part 2: Bromocarbons
bromine chemistry marine boundary layer stratosphere Bromocarbons
2008/11/21
In this second part of a series of articles dedicated to a detailed analysis of bromine chemistry in the atmosphere we address one (out of two) dominant natural sources of reactive bromine. The two ma...
Measurement-based modeling of bromine chemistry in the Dead Sea boundary layer – Part 2: The influence of NO2 on bromine chemistry at mid-latitude areas
bromine chemistry Dead Sea boundary layer NO2 mid-latitude areas
2008/11/17
Understanding the interaction between anthropogenic air pollution and Reactive Halogen Species (RHS) activity has had only limited support from direct field measurements, due to the fact that past fie...
