15 December 1995 Measurements of Antarctic ozone by POAM II

Abstract
The polar ozone and measurement (POAM II) instrument has been collecting data on the vertical distribution of ozone and other species in the polar stratosphere since its launch on the SPOT 3 satellite early in autumn 1993. POAM II makes solar occulation measurements at nine wavelengths from 35 to 1059 nm, allowing it to retrieve ozone, aerosols, water vapor, and nitrogen dioxide with about a 1 km vertical resolution. We will present data on the development and dissipation of the Antarctic ozone hole. We find that the bulk of the depletion occurred during the month of September, with ozone destruction rates exceeding 2% per day. The POAM II measurements clearly demonstrate the strong containment properties of the polar vortex.
