“…During winter 1982/83 an abnormal stratospheric ozone deficit was observed above northern extratropical latitude stations (Mantis et al, 1986). Again negative correlations were reported for lidar measurements of aerosol backscattering with stratospheric ozone contents (Adriani et al, 1987).…”

During winter 1982/83 and in early 1985, abnormal ozone deficiencies in the stratosphere were recorded at northern midlatitude stations. Ozone variations measured by ozonesondes at Hohenpeissenberg are analysed with respect to dynamic transport variations related to the quasibiennial oscillation (QBO). Atter the elimination of seasonal fluctuations, long-term trends and average QBO related variations, ozone time series are compared to particle surface area densities derived from lidar measurements of the stratospheric aerosol layer at Garmisch-Partenkirchen. The two stations are only 37 km apart. The analysis reveals that the 1985 ozone minimum is a transport effect, as well as most of the 1982/83 minimum. But at 17 to 20 km in 1982/83, 30 to 40% of the ozone deficiency is most probably related to the aerosol perturbation of the lower stratosphere following the April 1982 eruption of the Mexican volcano El Chich6n.

“…The pronounced decrease in total ozone following the Pinatubo (Philippines) eruption in the summer of 1991 has resulted in a number of papers dealing with the impact of this eruption on regional and global total ozone (Brasscur and Cn-anier, 1992;Bojkov et al, 1993;Chandra, 1993;Gleason et al, 1993;Grant et al, 1994;Holmann et al, 1994;Rodriguez et al, 1994;Zerefos et al, 1994;McCormick et al, 1995;Randel et al, 1995;Solomon et al, 1996). The other two major eruptions of the last 35 years, namely, Agung (Bali) in 1963 and E1 Chichon (Mexico) in 1982, received less attention in this regard, though Pittock (1965Pittock ( , 1966 recognized the possibility of a volcanic impact on total ozone following Agung, and others the probability of a volcanic impact following E1Chichon (Dutch, 1984;Bais et al, 1984;Mantis et al, 1986;Adriani et al, 1987;Hofinann and Solomon, 1989; Jager and Wege, 1990; Chandra and Stolarski, 1991). The occurrence of a very strong El Nino at nearly the same time as the El Chichon eruption confused the cause of the 1983 ozone decrease (Angell et al, 1985;Bojkov, 1987).…”

“…Reductions of midlatitude stratosphefic ozone concentration were observed following the volcanic eruptions of Mount Agung on March 17, 1963 [Grams and Fiocco, 1967;Pittock, 1965Pittock, , 1966, Fuego in October 1974 [Jager and Wege, 1990], and E1 Chich6n on March 28 to April 4, 1982[Datsch, 1985Mantis et al, 1986;Adriani et al, 1987;Angell, 1988;Newell and $elkirk, 1988; Jager and Wege, 1990; Chandra and $tolarski, 1991].

The large amount of sulfuric acid aerosol formed in the stratosphere by conversion of sulfur dioxide emitted by the eruption of Mount Pinatubo (15.14°N, 120.35°E) in the Philippines around June 15, 1991, has had a pronounced effect on lower stratospheric ozone in the tropics. Measurements of stratospheric ozone in the tropics using electrochemical concentration cell (ECC) sondes before and after the eruption and the airborne UV differential absorption lidar (DIAL) system after the eruption are compared with Stratospheric Aerosol and Gas Experiment II (SAGE II) measurements from several years before the eruption and ECC sonde measurements from the year prior to the eruption to determine the resulting changes. Ozone decreases of up to 33% compared with SAGE II climatological values were found to be directly correlated with altitude regions of enhanced aerosol loading in the 16‐ to 28‐km range. A maximum partial‐column decrease of 29±9 Dobson units (DU) was found over the 16‐ to 28‐km range in September 1991 along with small increases (to 5.9±2 DU) from 28 to 31.5 km. A large decrease of ozone was also found at 4° to 8°S from May to August 1992, with a maximum decrease of 33±7 DU found above Brazzaville in July. Aerosol data from the visible channel of the advanced very high resolution radiometer (AVHRR) and the visible wavelength of the UV DIAL system were used to examine the relationship between aerosol (surface area) densities and ozone changes. The tropical stratospheric ozone changes we observed in 1991 and 1992 are likely be explained by a combination of dynamical (vertical transport) perturbations, radiative perturbations on ozone photochemistry, and heterogeneous chemistry.
