The 15--16 June 1991 eruption of Mount Pinatubo delivered approximately 20 million metric tons of SO{sub 2} to the stratosphere. The SO{sub 2} plume from Mount Pinatubo straddled the equator resulting in a more symmetrical global distribution of the H{sub 2}SO{sub 4}-H{sub 2}O aerosol that results from the photochemical conversion of the SO{sub 2}. This paper follows the aerosol optical depth change over three-northern mid-latitude sites for the first sixteen months following the eruption. The technique to derive volcanic aerosol optical depth from ground-based measurements (which are, by their nature, total column aerosol optical depth measurements) follows the technique developed in an earlier parer to examine El Chichon aerosol. The three sites` time-dependent behavior is discussed and compared. Comparison of El Chichon and Mount Pinatubo aerosol optical depth change with time is also discussed for the one site that operated before, through, and after both eruptions.
