Stratospheric ozone depletion in the Antarctic region triggers intense changes in sea salt aerosol geochemistry

Molecular analysis of atmospheric microparticles in West Antarctica reveals chlorine-enriched aerosols are abundant in sea salt generated by photolytic products, while ice core records suggest increasing chlorine depletion since the onset of stratospheric ozone reduction.
