Stratospheric BrO profiles

A STRATOSPHERIC BrO CLIMATOLOGY BASED ON THE BASCOE 3D CHEMICAL TRANSPORT MODEL

A new climatology of stratospheric BrO profiles has been developed, with the aim to apply it to the retrieval of tropospheric BrO columns from space nadir measurements. The impact of the atmospheric dynamic on the stratospheric BrO distribution is treated by means of Bry/ozone correlations build from 3D-CTM model results, while photochemical effects are taken into account using stratospheric NO...

Remote 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 ...

Stratospheric HBr concentration profile obtained from farinfrared emission spectroscopy

Hydrogen bromide (HBr) is the principal bromine sink species for the ozone loss chemistry induced by brominecontaining ases in the stratosphere. We report a 1994 balloon-based measurement of the daytime stratospherie HBr profile between 20 and 36.5 km altitude. The average concentration result of 1.31 + 0.39 parts per trillion in volume (pptv) and an analysis for the concentration versus altitu...
