AB: We present the first observations of stratospheric Bromine Monoxide (BrO) from the Microwave Limb Sounder (MLS) instrument on the Aura spacecraft, launched on 15th July 2004. Bromine plays a significant role in stratospheric ozone chemistry and BrO is the dominant form of bromine in the daytime stratosphere. The significance of bromine is set to increase as stratospheric chlorine levels reduce following legislated reductions in emissions of chlorine source gasses. An overview is given of the MLS BrO observations. Initial results, such as monthly zonal means, are shown from the first few months of MLS observations. Comparisons with previous datasets and models are discussed.
