Synopsis

Over the Antarctic continent, ice clouds form in the cold winter darkness. On the surface of the cloud particles, chlorine nitrate and hydrogen chloride react and release chlorine. The chlorine then reacts with ozone forming chlorine monoxide and starting the catalytic ozone destruction cycle. The massive ozone loss results in the development of the Antarctic ozone hole. Note: Release of chlorine from reservoir gases over Antarctica. Animator: James W. Williams (GST), Jesse Allen (Raytheon), Greg Shirah (NASA/GSFC). Scientist: Mark Schoeberl (NASA/GSFC).
