Stratospheric sulfur aerosols are sulfur-rich particles which exist in the stratosphere region of the Earth's atmosphere. The layer of the atmosphere in which they exist is known as the Junge layer, or simply the stratospheric aerosol layer. These particles consist of a mixture of sulfuric acid and water. They are created naturally, following the oxidation of sulfur-containing gases, e.g. carbonyl sulfide and sulfur dioxide. When present in high levels, e.g. after a strong volcanic eruption such as the 1991 eruption of Mount Pinatubo, they produce a strong cooling effect by reflecting sunlight. This cooling may persist for a few years before the particles fall out.
