Large amounts of SO{sub 2} injected into the stratosphere by the El Chichon volcanic eruption greatly enhanced the sulfuric acid aerosol loading. According to laboratory studies, the increase in aerosol surface area would lead to a loss of ozone. Radiation measurements from the solar backscatter ultraviolet spectroradiometer are used to probe the absorbing and scattering properties of the stratosphere after the eruption. The backscattered radiation is enhanced for wavelengths greater than 290 nm, with a peak at about 302 nm. The enhancements associated with aerosol backscattering and ozone change can be separated. A decrease in column ozone of 8 to 30 Dobson units was deduced within the aerosol layer at an altitude between 20 and 30 km following the month of the eruption. 26 refs., 10 figs.
