The eruption of the Mexican volcano El Chichon in late March and early April of 1982 injected an unusually large amount of volcanic material into the stratosphere. This event demonstrates for the first time that a relatively small but sulfur-rich volcanic eruption can produce a dense, widespread stratospheric cloud. Sulfuric acid aerosol is formed by the photochemical reaction of sulfur gases released by a volcano with water vapor in the atmosphere. The aerosol causes a decrease in the mean global temperature because the droplets both absorb solar radiation and scatter it back into space. Attention is given to details concerning the volcanic eruption, the relation of El Chichon to the Mexican and Guatemalan volcanic belts, sources for the sulfur erupted by the volcano, and the mechanisms involved in the formation of sulfuric acid.
