Short summary
We show the first simultaneous observations of triple oxygen isotopic compositions of atmospheric sulfate, nitrate, and ozone at Dumont d'Urville, coastal Antarctica. The contrasting seasonal trends between oxygen isotopes of ozone and those of sulfate and nitrate indicate that these signatures in sulfate and nitrate are mainly controlled by changes in oxidation chemistry. We also discuss the specific oxidation chemistry induced by the unique phenomena at the site.
