      abstract     = {For the first time, results of four stratospheric BrO
                      profiling instruments, are presented and compared with
                      reference to the SLIMCAT 3-dimensional chemical transport
                      model (3-D CTM). Model calculations are used to infer a BrO
                      profile validation set, measured by 3 different balloon
                      sensors, for the new Envisat/SCIAMACHY (ENVIronment
                      SATellite/SCanning Imaging Absorption spectroMeter for
                      Atmospheric CHartographY) satellite instrument. The balloon
                      observations include ( a) balloon-borne in situ resonance
                      fluorescence detection of BrO ( Triple), (b) balloon-borne
                      solar occultation DOAS measurements ( Differential Optical
                      Absorption Spectroscopy) of BrO in the UV, and ( c) BrO
                      profiling from the solar occultation SAOZ ( Systeme
                      d'Analyse par Observation Zenithale) balloon instrument.
                      Since stratospheric BrO is subject to considerable diurnal
                      variation and none of the measurements are performed close
                      enough in time and space for a direct comparison, all
                      balloon observations are considered with reference to
                      outputs from the 3-D CTM. The referencing is performed by
                      forward and backward air mass trajectory calculations to
                      match the balloon with the satellite observations. The
                      diurnal variation of BrO is considered by 1-D photochemical
                      model calculation along the trajectories. The 1-D
                      photochemical model is initialised with output data of the
                      3-D model with additional constraints on the vertical
                      transport, the total amount and photochemistry of
                      stratospheric bromine as given by the various balloon
                      observations. Total [Br-y]=(20.1 +/- 2.5) pptv obtained from
                      DOAS BrO observations at mid-latitudes in 2003, serves as an
                      upper limit of the comparison. Most of the balloon
                      observations agree with the photochemical model predictions
                      within their given error estimates. First retrieval
                      exercises of BrO limb profiling from the SCIAMACHY satellite
                      instrument on average agree to around $20\%$ with the
                      photochemically-corrected balloon observations of the remote
                      sensing instruments (SAOZ and DOAS). An exception is the in
                      situ Triple profile, in which the balloon and satellite data
                      mostly does not agree within the given errors. In general,
                      the satellite measurements show systematically higher values
                      below 25 km than the balloon data and a change in profile
                      shape above about 25 km.},
