Vertical profiles of CFC-113 obtained by gaschromatographic analyses of stratospheric air samples collected during five balloon flights carried out during 1982, 1983 and 1984 are presented. Neon-cooled cryogenic samplers of MPAE and KFA, respectively, were launched on 20 September (MPAE) and 21 October (KFA) 1982 and 1 October 1984 (MPAE), at Aire sur 1'Adour, France (44°N). On 10 September 1983, an intercomparison flight of MPAE and KFA samplers was carried out at the same balloon facility as part of the MAP/GLOBUS campaign. An average 1982-1984 midlatitude profile of CFC-113 obtained by averaging the results of all flights shows mixing ratios decreasing from 23 pptV at the tropopause to 1 pptV at 32 km. Results obtained with a time-dependent 1-D model based on CFC-113 global emission rates evaluated by Wuebbles (1983, PhD Thesis, University of California; Lawrence Livermore Laboratory Report UCRL-53423) are in good agreement with our measured distribution.
