abstract = {Measurements in the vicinity of the polar jet stream during
the STREAM 1998 campaign in Timmins, Canada, show that
during the flight on 15 July, a deep intrusion of
stratospheric air into the troposphere occurred. At the edge
of the deep intrusion dehydration was observed. The
dehydration can be identified in tracer–tracer
correlations of H2O and O3 and by the comparison of these
correlations with correlations of H2O and O3 derived from
two other flights of the STREAM 1998 campaign. Trajectories,
calculated backwards for 10 days starting at each point of
the measurement for the flight on 15 July, show that the
saturation ratios required for homogeneous freezing are
reached. However, box model simulations along the
trajectories indicate no substantial growth of H2SO4/H2O
particles due to H2O uptake. Since ice nuclei were not
measured during the campaign, it cannot be precisely
determined which freezing process, heterogeneous or
homogeneous, is responsible for the formation of the ice
particles. Most likely, both processes were involved in the
formation of ice particles that led to the observed
dehydration on 15 July 1998.},
