We discuss measurements of stratospheric BrO obtained by the Microwave Limb Sounder (MLS) on the Aura
satellite. These measurements span an altitude range of 32 to 42 km. Previous validation of MLS BrO in the mid-
latitudes and tropics took advantage of the diurnal variation of BrO at those latitudes to remove large biases in the
data. For winter and summer polar BrO, we cannot remove biases that way. Therefore we use a different method,
estimating the biases from non-polar regions, as well as from polar regions in the spring and fall, when polar
BrO undergoes a diurnal variation. We then subtract these estimates from the MLS BrO data. To compare polar
MLS BrO measurements with lower-altitude measurements obtained by the balloon-borne instruments DOAS,
SAOZ-BrO, and SLS, we use a photochemical model to infer total inorganic bromine (Bry). Since Bry, unlike BrO,
should remain approximately constant with altitude, it provides a proxy for comparison.
