Chlorine nitrate

From Glossary of Meteorology

chlorine nitrate

A chlorine compound with chemical formula ClNO3, often written as ClONO2.

It is of importance as a reservoir species for reactive chlorine and nitrogen in the lower and middle stratosphere. It is formed in the termolecular reaction of ClO with NO2 and is destroyed via photolysis by near-UV solar radiation or via heterogeneous reactions on polar stratospheric clouds and aerosol particles.
