      abstract     = {Chemical ozone loss in the Arctic stratosphere was
                      investigated for the twelve years between 1991 and 2003
                      employing the ozone-tracer correlation method. For this
                      method, the change in the relation between ozone and a
                      long-lived tracer is considered for all twelve years over
                      the lifetime of the polar vortex to calculate chemical ozone
                      loss. Both the accumulated local ozone loss in the lower
                      stratosphere and the column ozone loss were derived
                      consistently, mainly on the basis of HALOE satellite
                      observations. HALOE measurements do not cover the polar
                      region homogeneously over the course of the winter. Thus, to
                      derive an early winter reference function for each of the
                      twelve years, all available measurements were additionally
                      used; for two winters climatological considerations were
                      necessary. Moreover, a detailed quantification of
                      uncertainties was performed. This study further demonstrates
                      the interaction between meteorology and ozone loss. The
                      connection between temperature conditions and chlorine
                      activation, and in turn, the connection between chlorine
                      activation and ozone loss, becomes obvious in the HALOE HCl
                      measurements. Additionally, the degree of homogeneity of
                      ozone loss within the vortex was shown to depend on the
                      meteorological conditions.Results derived here are in
                      general agreement with the results obtained by other methods
                      for deducing polar ozone loss. Differences occur mainly
                      owing to different time periods considered in deriving
                      accumulated ozone loss. However, very strong ozone losses as
                      deduced from SAOZ for January in winters 1993-1994 and
                      1995-1996 cannot be identified using available HALOE
                      observations in the early winter. In general, strong
                      accumulated ozone loss was found to occur in conjunction
                      with a strong cold vortex containing a large volume of
                      possible PSC existence ( V-PSC), whereas moderate ozone loss
                      was found if the vortex was less strong and moderately warm.
                      Hardly any ozone loss was calculated for very warm winters
                      with small amounts of V-PSC during the entire winter. This
                      study supports the linear relationship between VPSC and the
                      accumulated ozone loss reported by Rex et al. ( 2004) if
                      VPSC was averaged over the entire winter period. Here,
                      further meteorological factors controlling ozone loss were
                      additionally identified if VPSC was averaged over the same
                      time interval as that for which the accumulated ozone loss
                      was deduced. A significant difference in ozone loss ( of
                      approximate to36 DU) was found due to the different duration
                      of solar illumination of the polar vortex of at maximum 4
                      hours per day in the observed years. Further, the increased
                      burden of aerosols in the atmosphere after the Pinatubo
                      volcanic eruption in 1991 significantly increased the extent
                      of chemical ozone loss.},
