Reservoir compounds

From Glossary of Meteorology

reservoir compounds

Any of a series of relatively long-lived compounds that sequester more reactive oxides of nitrogen, hydrogen, and halogen in the stratosphere.

Examples include 1) chlorine nitrate, ClNO3, which ties up both ClO and NO2, and 2) HO2NO2, which is a HO2 and NO2 reservoir. The presence of these compounds serves to mediate the ability of the more reactive oxides to destroy stratospheric ozone, or to produce tropospheric ozone.
