abstract = {Chlorine monoxide (ClO) plays a key role in stratospheric
ozone loss processes at midlatitudes. We present two
balloon-borne in situ measurements of ClO conducted in
northern hemisphere midlatitudes during the period of the
maximum of total inorganic chlorine loading in the
atmosphere. Both ClO measurements were conducted on board
the TRIPLE balloon payload, launched in November 1996 in
Leon, Spain, and in May 1999 in Aire sur l'Adour, France.
For both flights a ClO daylight and night-time vertical
profile was derived over an altitude range of approximately
15 - 35 km. ClO mixing ratios are compared to model
simulations performed with the photochemical box model
version of the Chemical Lagrangian Model of the Stratosphere
(CLaMS). Simulations along 24-hour backward trajectories
were performed to study the diurnal variation of ClO in the
midlatitude lower stratosphere. Model simulations for the
flight launched in Aire sur l'Adour 1999 show an excellent
agreement with the ClO measurements. For the flight launched
in Leon 1996, an overall good agreement is found, whereas
the flight is characterized by a more complex dynamical
situation due to a possible mixture of vortex and non-vortex
air. We note that for both flights at solar zenith angles
greater than 86 degrees - 87 degrees simulated ClO mixing
ratios are higher than observed ClO mixing ratios. However,
the present findings indicate that no substantial
uncertainties exist in midlatitude chlorine chemistry of the
stratosphere.},
