AB: The current uncertainty in the total bromine loading of the stratosphere is a significant barrier to the full understanding of the stratospheric ozone budget. Observed bromine abundances in the stratosphere generally exceed the levels calculated by current models. Possible explanations for this discrepancy include contributions from sources not included in the models, such as very short lived halogens or inorganic bromine species in the troposphere. This paper describes new total inorganic bromine (Br_y) abundance estimates infered from observations of upper stratospheric BrO made by the EOS Microwave Limb Sounder on Aura using model estimates of the BrO to Bry ratio.
