Interactive comment on “Horizontal and vertical structure of reactive bromine events probed by bromine monoxide MAX-DOAS spectroscopy” by William R. Simpson et al
نویسنده
چکیده
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 250-m resolution MODIS

متن کاملThe role of bromine and chlorine chemistry for arctic ozone depletion events in Ny-AÊ lesund and comparison with model calculations
During the Arctic Tropospheric Ozone Chemistry (ARCTOC) campaigns at Ny-AÊ lesund, Spitsbergen, the role of halogens in the depletion of boundary layer ozone was investigated. In spring 1995 and 1996 up to 30 ppt bromine monoxide were found whenever ozone decreased from normal levels of about 40 ppb. Those main trace gases and others were speci®cally followed in the UV-VIS spectral region by di...
متن کاملRemote Sensing of Bromine Monoxide in Relation to Boundary-layer Halogen Chemistry
Remote sensing of bromine monoxide (BrO) from the Ozone Monitoring Instrument (OMI) and other satellite instruments opens the possibility to extend our understanding of atmospheric halogen chemistry from local-scale studies to global scales. In the Arctic springtime boundary layer, these bromine monoxide radicals and bromine atoms are known to destroy ozone [1] and oxidize mercury [2], leading ...
متن کاملCarbonate precipitation in brine – a potential trigger for tropospheric ozone depletion events
Tropospheric ozone depletion events (ODEs) at high latitudes were discovered 20 years ago and are attributed to bromine explosions. However, an unresolved issue is the explanation of how the acid-catalyzed reaction cycle is triggered in atmospheric particles derived from alkaline sea water. By simulating the chemistry occuring in polar regions over recently formed sea ice, we can model successf...
