Abstract

For the high-altitude ER-2 observations of ClO, O3, H2O, N2O, NO(y), CFCl3, and CF2Cl2 during August 17-September 29, 1987 and January 3-February 20, 1989, condensation nuclei, wind, temperature, and pressure are presented as averages of all flights. The data are displayed as vertical profiles over the airfields Punta Arenas (53 deg S, 71 deg W) and Stavanger (59 deg N, 6 deg E) and within the vortices at about 72 deg S and 78 deg N, respectively. It is shown that the Antarctic ozone hole was caused by chlorine chemistry whose balance was altered by reactions on the surface in crystals in polar stratospheric clouds. Similar processes were observed in the Arctic, whose vortex is thus primed for ozone loss.
