The ESa Sounder Campaign (ESSenCe) conducted field measurements utilizing the high-altitude research aircraft Geophysica to quantify processes that control the composition and structure of the mid to upper troposphere and lower stratosphere (UTLS). It took place in Kiruna/Sweden in December 2011. This activity supports the in-flight testing of a new imaging infra-red limb-sounder (GLORIA) and a millimetre-wave limb-sounder (MARSHALS).
This paper gives a general overview about the ESSenCe campaign, the aircraft instrumentation, the meteorological situation as well as the GLORIA instrument performance. GLORIA dynamics mode data is presented in some more depth. This data indicates a thin vertical structure at about 14 km extending about 500m vertically. It is most likely an intrusion of deeper stratospheric air, as indicated by relatively large ozone and HNO3 values together with small CFC-11 values. The observation of such fine structures highlights the unprecedented vertical resolution of GLORIA data and demonstrates the potential of imaging Fourier Transform Spectroscopy for limb viewing instruments to observe small scale mixing events.
