      abstract     = {Inorganic bromine species form the second most important
                      halogen family affecting stratospheric ozone (WMO, 2003).
                      Although the stratospheric bromine mixing ratio is about two
                      orders of magnitude lower than the chlorine one, bromine has
                      much higher ozone depleting potential (factor of about 45)
                      compared to chlorine. This study reports and discusses
                      atmospheric bromine monoxide, BrO, measurements in the
                      altitude range 15-30 km performed by the balloon-borne
                      instrument TRIPLE and aircraft instrument HALOX employing
                      the chemical conversion resonance fluorescence technique,
                      which is the only proven in-situ technique for the
                      measurements of BrO. 57 HALOX flights have been performed in
                      the frame of five field campaigns ranging from the Arctic to
                      tropics. Three TRIPLE flights were carried out at high and
                      mid latitudes in the frame of the SCIAMACHY (SCanning
                      Imaging Absorption spectroMeter for Atmospheric
                      CHartographY) validation. Calibration, consistency checks,
                      data analysis, and error assessment for the in-situ
                      measurements are described. The balloon measurements have
                      yielded vertical profiles of BrO between 15 and 30 km
                      altitude at northern mid- and at arctic latitudes. From the
                      aircraft measurements a meridional BrO distribution from
                      tropical to the arctic latitudes between 15 and 20 km
                      altitude was obtained. For the SCIAMACHY validation the
                      TRIPLE BrO profiles have been photochemically corrected by
                      means of the Jülich CLaMS (Chemical Lagrangian Model of the
                      Stratosphere) model in order to reflect the diurnal
                      variation of BrO and adjust the profiles to the
                      photochemical conditions of the corresponding SCIAMACHY
                      measurements. Hereby appropriate SCIAMACHY profiles have
                      been found to be systematically higher than the TRIPLE
                      profiles but mostly within the bounds of the accuracies of
                      both techniques. Improvements in the satelite retrieval
                      procedures are ongoing. [...]},
