      abstract     = {In this thesis, the chemical ozone loss in the Arctic
                      stratosphere was investigated for twelve years between
                      1991-92 and 2002-03. The accumulated local ozone loss and
                      the column ozone loss were consistently derived using the
                      ozone-tracer correlation (TRAC) technique. This technique
                      considers the relation between ozone and a long-lived tracer
                      during the lifetime of the polar vortex. Results are
                      presented on the basis of observations obtained from two
                      solar occultation satellite instruments: ILAS (Improved Limb
                      Atmospheric Spectrometer) aboard the ADEOS satellite
                      (Advanced Earth Observing Satellite) and HALDE (Halogen
                      Occultation Experiment) aboard the UARS satellite (Upper
                      Atmosphere Research Satellite). The HALDE observations used
                      in the present work have been available since October 1991.
                      The instrument made measurements during a period of a few
                      days every two or three months in high northern latitudes
                      during the entire period between 1991 and 2003. The ILAS
                      instrument performed mear surements continuously from
                      November 1996 to June 1997 in the high latitude region of
                      both hemispheres. In the present work, the TRAC method was
                      confirmed against criticism raised in the past. The improved
                      and extended method permits both a reduction and a better
                      quantification of uncertainties. New procedures implemented
                      in the method allow the ozone loss for the winter to be
                      calculated, in case where no results could have been derived
                      in the past. Therefore, a consistent analysis is possible
                      for the twelve winters. An intensive analysis of chemical
                      ozone loss is performed considering as an example the winter
                      1996-97, for which measurements from both HALDE and ILAS are
                      available. The ILAS observations allow a detailed analysis
                      of the temporal evolution of the ozone-tracer correlation
                      inside the polar vortex for the first time and in particular
                      of the development of the early vortex. Especially the
                      influence of mixing between vortex air and air from outside
                      the vortex is discussed. The evolution of significant
                      PSC-related chemical ozone loss can be followed over the
                      entire lifetime of the vortex, from mid-February to May 1997
                      from ILAS observations. HALDE measurements are available
                      between March and May 1997. Partly large differenced between
                      the two data sets are analysed. Both data sets consistently
                      show a distinct inhomogeneity in the derived ozone loss
                      inside the vortex in spring 1997, which is a specific
                      feature in comparison to the other observed winters between
                      1991-92 and 2002-03. During these twelve winters the ozone
                      loss was consistently derived mainly on the basis of HALDE
                      observations. With the use of the ozone-tracer [...]},
