In June 2024 TPEx (TropoPause compositon gradients and mixing Experiment) starts as the central measurement campaign of the TPChange project. This project focusses on water vapor distribution across central Europe, mixing at and across the tropopause, vertical transport of Aerosols and trace species from the boundary layer to the UTLS as well as UTLS composition and new particle formation. In addition, sources of aerosols and ice-nucleating particles shall be appointed. The measurements of aerosols and trace gases will be done by a towed sensor shuttle (AIRTOSS) and instruments mounted in a wingpod (KNUFFI) attached to the research platform Learjet 35A-CGFD. enviscope is responsible for the adaptation of the instrumentation, the necessary certification in co-operation with the Design Organisation of ACJ, and supports the field mission and the operation of the a/c by our partner GFD.
