The June 1991 eruption of Mt. Pinatubo heavily affected the entire stratosphere, and the resulting aerosol layer caused noteworthy impacts on the climate and chemical processes throughout the atmosphere. One month before the eruption of the Mt. Pinatubo volcano, there was a relatively clear atmosphere. During the month of the eruption, the volcanic material was concentrated in the Tropics. A year after the eruption, aerosols spread across virtually the entire globe. The aerosol layer had warmed the local stratosphere by about 2.5 - 3 degrees Celsius within three months after the eruption. One year and 8 months after the eruption, there were still relatively high world-wide levels of sulfuric acid aerosol particles. Notice the difference: very thin pre-eruption levels are shown in green and very thick levels are shown in red. Read more about:
