V. Bergeret et al., ANTARCTIC OZONE SEASONAL-VARIATION ANALYSIS IN THE LOWER STRATOSPHEREFROM LIDAR AND SOUNDING MEASUREMENTS AT DUMONT DURVILLE, Comptes rendus de l'Academie des sciences. Serie 2. Sciences de la terre et des planetes, 326(11), 1998, pp. 751-756
Average subsidence in the Antarctic lower stratosphere for the austral
fall of 1994 and 1996 and ozone destruction rates during the spring a
re derived from ozone measurements made at Dumont d'Urville (140.1E, 6
6.4S). The comparison with POAM II data suggests that ozone destructio
n within the vortex starts earlier on the edge than in the centre. The
vortex sampling in 1996 allows us to study the vortex confinement and
to confirm its role of isolating barrier above 400 K. (C) Academie de
