Abstract

Ozone Variations at the Zugspitze (2962 m a.s.l.) during 1996-1997 A contribution to subproject TOR-2 HE Scheel, R. Sladkovic and H-J Kanter Fraunhofer-Institutfur Atmospharische Umweltforschung (IFU), D-82467 Garmisch-Partenkirchen, Germany Introduction As known from previous studies, which also included species such as carbon monoxide and the tracer beryllium-7 (^Be), the major short-term variations of ozone at the Zugspitze mountain site are related to (i) ozone removal in polluted air or photochemical ozone production, (ii) advection of southerly air containing low ozone concentrations, and (iii) subsidence of ozone-rich air in response to stratospheric intrusions. Ozone variations due to either of these processes, and thus air masses of completely different characteristics, are often observed within a few hours. This underlines the complex vertical structure of Og concentrations in
