Chemistry and transport processes in the south polar stratosphere have been intensively studied since discovery of the seasonal {open_quotes}ozone hole{close_quotes} appearing over Antarctica. Nevertheless, large gaps still exist in our knowledge of the dynamical and chemical behavior of the polar winter vortex. This behavior is responsible for much of the prior processing of air, and the processing makes possible the formation of a springtime ozone hole. The work described here was intended to fill some of these gaps by frequently monitoring the behavior of several trace gases over as much of a full year cycle as possible, from a central position within the annually forming winter vortex region. The species covered (not all for the full duration of the observations) were ozone, nitrogen dioxide, nitrous oxide, nitric acid, and chlorine monoxide. An upper limit for hydrogen peroxide was also determined by an unsuccessful attempt to detect it. 7 refs.
