abstract = {Water vapour and ozone in-situ observations in the tropical
tropopause layer (TTL) during the three tropical campaigns
SCOUT-O3, AMMA and TroCCiNOx are reconstructed from diabatic
and kinematic backtrajectories, with the reconstruction
method for the tracer fields based on freeze-drying and
photochemichal ozone production. The results using diabatic
trajectories show that both water vapour and ozone in-situ
observations can be well reconstructed from trajectories.
Consequentially, in-situ observations agree with the
assumption of freeze-drying due to the large-scale
temperature field as the main control mechanism for water
vapour and photochemical production and transport as main
control mechanisms for tropical ozone. The kinematic ozone
reconstruction, however, shows a large high-bias during
SCOUT-O3 and a too strong variability during all campaigns,
due to excessive transport of stratospheric ozone into the
TTL. We conclude that kinematic reconstructions of in-situ
observations are less reliable than diabatic, due to
unrealistic inhomogeneities in the velocity field.},
