GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere) is an airborne imaging Fourier Transform Spectrometer instrument developed at Karlsruhe Institute of Technology and Research Center Juelich, Germany. Depending on the scientific aims, the instrument enables measurements in limb and nadir geometry with high spectral resolution and lower spatial coverage (chemistry mode) or high spatial coverage and lower spectral resolution (dynamic mode). Up to now, GLORIA successfully accomplished three scientific field campaigns with flights carried out under various atmospheric conditions and at wide range of latitudes and seasons and confirmed its high technical and scientific capability. The huge amount of data acquired during the campaigns enables extensive research on transport and mixing in the extratropical UTLS region, biomass burning emissions, stratospheric polar ozone chemistry and the interaction between the Indian monsoon and the changing climate. The results of the GLORIA technical tests and field campaigns support the feasibility studies of PREMIER (PRocess Exploration through Measurements of Infrared and millimetre-wave Emitted Radiation) candidate mission for the ESA’s seventh Earth Explorer. Here, we describe the GLORIA data processing developed at Karlsruhe Institute of Technology, present spatial distribution cross sections of atmospheric constituents measured in chemistry mode during the TACTS and ESMVal field campaigns (summer 2012) and compare the results with collocated measurements.
