Abstract

Recently, episodic destruction of boundary-layer ozone has been observed in the arctic [Barrie et al., 1989, Barrie et al., 1988, Bottenheim et al., 1990, Mickle et al., 1889, Oltmans et al., 1983]. Those episodes, when ozone levels drop from the normal 30–40 ppb to unmeasurable (3< ppb) levels, appear to be associated with high concentrations of “filterable bromine” (bromine that can be collected on cellulose filters). While it is not clear what the exact nature of filterable bromine is, it was hypothesized by several authors [Barrie et al., 1988, Bottenheim et al 1990] that the active component of filterable bromine might be BrO radicals.
