Abstract. The three-dimensional quantification of small-scale processes in the upper troposphere and lower stratosphere is one challenges current atmospheric research requires development new measurement strategies. This work presents first results from newly developed Gimballed Limb Observer for Radiance Imaging Atmosphere (GLORIA) obtained during ESSenCe (ESa Sounder Campaign) TACTS/ESMVal (TACTS: Transport composition troposphere/lowermost stratosphere, ESMVal: Earth System Model Validation) aircraft campaigns. focus this on so-called dynamics-mode data characterized by a medium-spectral very-high-spatial resolution. retrieval strategy derivation two- constituent fields presented. Uncertainties main targets (temperature, O3, HNO3, CFC-12) their spatial resolution are discussed. During ESSenCe, high-resolution two-dimensional cross-sections have been obtained. Comparisons to collocated remote-sensing situ indicate good agreement between sets. TACTS/ESMVal, tomographic flight pattern sense an intrusion stratospheric air deep into was performed.
