Paper Abstract

The increase of particle surface-area concentration in the stratosphere after strong volcanic eruptions is believed to exacerbate the manmade ozone depletion because of the modified conditions for heterogeneous chemical reactions. To quantify this effect longterm observations of both particle surface-area and ozone concentrations are performed since the eruption of Mt. Pinatubo in June 1991. Surface-area concentrations are measured with a Raman elastic- backscatter lidar at Geeshacht (53.5 degrees N). Ozone measurements are made with ECC sondes by the German Weather Service at Lindenberg (52 degrees N). Surface-area concentrations of the order of 20 micrometers 2cm-3 have been found between 10 and 20 km height during the first two years after the Mt. Pinatubo eruption. In the same height region, ozone losses of more than 20% during winter and spring seasons 1991/92 and 1992/93 have been observed.
