Global measurements of bromine monoxide and comparison with model results — •Ninad Sheode — 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 significant role in ozone depletion, the measurements of bromine species have been sparse. And hence the chemical mechanisms of bromine chemistry have also not been thorougly validated.

SCIAMCHY launched on board ENVISAT in March 2002 is measuring bromine monoxide globally for the first time. Bromine monoxide forms 40 to 70 percent of total inorganic bromine in the atmosphere. The global measurements of bromine monoxide give us a good opportunity to understand and validate our understanding of bromine chemistry.
