Chlorine monoxide radical
From Glossary of Meteorology
chlorine monoxide radical
A reactive radical species with chemical formula ClO.
Chlorine monoxide is an important inorganic chlorine compound in the stratosphere. This species is produced in the reaction of Cl atoms with ozone. Its conversion back to Cl without reforming O3 (e.g., via reaction with O atoms) results in chlorine-catalyzed ozone loss in the stratosphere.
