Global measurements of bromine monoxide and comparison with model results — •Ninad Sheode, Bjoern-Martin Sinnhuber, Alexei Rozanov, and John Burrows — Univ. Bremen, IUP/IFE, Otto-Hahn Alle, 28329, Bremen, Germany

Bromine compounds play an important role in the depletion of stratospheric ozone. They are more efficient at destroying ozone at per molecule level than for an equivalent amount of chlorine. However, despite their important role in ozone depletion , the measurements of bromine species have been sparse. And hence the chemical mechanisms of bromine chemistry have also not been thoroughly validated.

SCIAMACHY, launched on board ENVISAT in March 2002, is measuring bromine monoxide (BrO) globally for the first time. BrO forms 40-40 percent of total inorganic bromine in the atmosphere. the global measurements of BrO give us a good opportunity to understand and validate our understanding of bromine chemistry.
