Abstract

The principal gaseous components of volcanic emissions are water, carbon dioxide, and sulfur (as SO₂, H₂S, and OCS). Only the sulfur gases are significant on a global scale when compared with other natural and anthropogenic sources and represent less than 10% of the input. However, sulfur compounds that reach the stratosphere, when combined with volcanic or meteoric dust particles, are the main precursors of stratospheric aerosols. Those aerosols play a critical role in the regulation of incoming solar radiation and consequently global warming.
