Short summary
The paper details novel mass spectrometric measurements with AIMS-TG aboard the new German research aircraft HALO. The measurements comprise a wide range of tracers with characteristic source regions. Using these tracers, stratospheric and tropospheric air in the UTLS is tagged. The instrument is equipped with a new discharge ionization source, an in-flight calibration and improved transmission of adhesive gases like HNO3 and HCl. AIMS was built to characterize transport and mixing in the UTLS.
