Natural sulfur cycle

From Glossary of Meteorology

natural sulfur cycle

Conceptualization of the processes associated with the production and loss of sulfur gases in the atmosphere.

The cycle consists of 1) the emission of reduced sulfur gases (such as dimethyl sulfide, carbonyl sulfide) by biological material; 2) the oxidation of these gases to sulfur dioxide or sulfuric acid in the atmosphere; and 3) the subsequent deposition of these acidic species to the earth's surface.
