Abstract

Bromine compounds play an important role in the catalytic destruction of stratospheric ozone. SCIAMACHY/ENVISAT provides for the first time a global view on stratospheric bromine monoxide (BrO). Here we present a first climatology of stratospheric BrO derived from two years of SCIAMACHY observations. Using a photochemical model constrained by simultaneous NO2 observations from SCIAMACHY a budget of the stratospheric bromine loading is derived from the BrO observations.
