      abstract     = {Novel airborne in situ measurements of inorganic chlorine,
                      nitrogen oxide species, and ozone were performed inside the
                      lower Antarctic polar vortex and at its edge in September
                      2012. We focus on one flight during the Transport and
                      Composition of the LMS/Earth System Model Validation
                      (TACTS/ESMVal) campaign with the German research aircraft
                      HALO (High-Altitude LOng range research aircraft), reaching
                      latitudes of 65°S and potential temperatures up to 405 K.
                      Using the early winter correlations of reactive trace gases
                      with N2O from the Atmospheric Chemistry Experiment-Fourier
                      Transform Spectrometer (ACE-FTS), we find high depletion of
                      chlorine reservoir gases up to $∼40\%$ (0.8 ppbv) at 12 km
                      to 14 km altitude in the vortex and 0.4 ppbv at the edge in
                      subsided stratospheric air with mean ages up to 4.5 years.
                      We observe denitrification of up to 4 ppbv, while ozone was
                      depleted by 1.2 ppmv at potential temperatures as low as 380
                      K. The advanced instrumentation aboard HALO enables
                      high-resolution measurements with implications for the
                      oxidation capacity of the lowermost stratosphere.},
