ClONO₂, ClNO₃

Definition

Chlorine Nitrate (ClONO₂) is of importance as a reservoir species (more abundant stable compound) for reactive chlorine and nitrogen in the lower and middle stratosphere.
It is formed in the molecular reaction of ClO with NO2 and is destroyed via photolysis by near-UV solar radiation. ClONO₂ reacts rapidly with HCl on polar stratospheric clouds and aerosol particles during polar night and provides active chlorine, which depletes local ozone.
