      abstract     = {The chemical composition of the Upper Troposphere and Lower
                      Stratosphere (UTLS) region and the dynamical processes
                      occurring within it have a particularly strong effect on
                      radiative forcing, and hence surface climate. A lack of
                      quantitative understanding of the region around the
                      tropopause, and especially of exchange of trace constituents
                      between the stratosphere and the troposphere, severely
                      limits the predictive capabilities of current climate
                      models. More and spatially better resolved observations are
                      needed in order to close this gap. To this end, the
                      Gimballed Limb Observer for Radiance Imaging of the
                      Atmosphere (GLORIA) was developed in a collaboration between
                      the German research centres Forschungszentrum Jülich GmbH
                      and Karlsruher Institut für Technologie. GLORIA is the
                      descendant of the highly successful MIPAS and CRISTA
                      instruments and has been designed with both chemical and
                      dynamical analysis of the UTLS in mind. The imaging
                      technology utilised by GLORIA and the resulting high data
                      rate present unprecedented opportunities for data analysis,
                      but also challenges for the processing of the recorded
                      measurements. In this work, a new integrated data processing
                      system designed for GLORIA is presented, as well as novel
                      techniques for calibration and diagnosis. As an application
                      of the new data processing chain, a polar flight from the
                      combined TACTS/ESMVal campaign is presented which was
                      performed on September 23rd, 2012, along a trajectory mostly
                      above the Scandinavian peninsula. A selection of
                      measurements from this flight is processed into calibrated
                      spectra and then analysed further using the JURASSIC2
                      retrieval processor. Retrieved cross-sections of ozone,
                      nitric acid, water vapour and atmospheric temperature are
                      shown and compared with calculations from the Chemical
                      Lagrangian Model of the Stratosphere (CLaMS), as well as
                      potential vorticity from the European Centre for
                      Medium-Range Weather Forecasts (ECMWF). The measurements
                      reveal a highly inhomogeneous UTLS region suggesting that
                      tropospheric air masses have been transported into the polar
                      stratosphere, which is also indicated by the ECMWF data and
                      further supported by CLaMS trajectory calculations. Two main
                      structures can be identified. One is an anticyclone
                      resulting from a mid-latitude wave-breaking event that
                      transported tropospheric air into the observed region. The
                      other is a vertically confined cyclone of seemingly
                      stratospheric origin. The results are a successful
                      application of both the newly-developed processing chain as
                      well as the GLORIA instrument itself and highlights
                      GLORIA’s ability to observe the effect of dynamic and
                      transport processes in the UTLS.},
