(TropoPause compositon gradients and small scale mixing Experiment)

TPEx is the central field campaign of the TPChange research center. It will take place in June 2024 out of Hohn (Schleswig-Holstein) with measurement flights in the time window from June 10 to 21.

 The scientific questions are

  • Water vapor distribution in the UTLS region across central Europe
  • Identification of mixing at and across the tropopause induced by diabatic processes
  • Vertical transport of arosols and trace species from the boundary layer to the UTLS (e.g. by convection or frontal uplift) and effect of UTLS composition and new particle formation events
  • Source apportionment of aerosols and ice-nucleating particles (INPs) for understanding the main pathways of transport towards UTLS
