lithosphere
In this way, these aerosols act much like the polar stratospheric clouds with reactions occurring on their surfaces. The resultant active chlorine species, such as ClO and ... Some scientists argue that the amount of chlorine put into the stratosphere by a major volcanic eruption rivals that of anthropogenically produced chlorine. In the 1980s, emissions of CFCs added chlorine ...

CRU Information Sheet no. 13: Volcanoes and their effect on climate
Benjamin Franklin, in 1783, first postulated that major volcanic eruptions affect climate, after the eruption of the Laki volcano in Iceland. Ironically, most of ... the response of the climate system to a major volcanic event. Earlier work, from the 1960s onwards, suggested that when eruption clouds reach the lower stratosphere (about 20-25km aloft) the ...

Science and the Environment Bulletin: The Telltale Cloud
Developed in the wake of the 1986 nuclear accident at Chernobyl, this advanced technology has many and varied applications including the support of safe aircraft operations, such as forecasts of volcanic ash clouds travelling around the earth following an eruption. In the case of a nuclear explosion, computer models can estimate ...

Such natural phenomena as seasonality, winds and volcanic eruptions also affect the distribution of the ozone in the atmosphere. How does the action ... in winter warmer than it is in the Antarctic, which prevents the formation of stratospheric clouds. This, in turn, is caused by differences in the land-ocean distribution, and atmospheric flow ...
