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.},
