The Story of Ozone Depletion

The Antarctic ozone hole is caused by human-produced chlorine-containing chlorofluorocarbons (CFCs) and bromine-containing halons. These compounds had a variety of commercial uses, including hair sprays, refrigerants, and fire suppressants.

This story about the cause of ozone depletion was originally developed for the NASA hyperwall, where nine different animations can be shown simultaneously. The animations shown here are derived from the Goddard Earth Observing System (GEOS) model and cover two periods. The first period is from August through November 2004, and the second is from December 2004 through March 2005. The first period animations are shown on this page. The second period animations may be downloaded through the Download links below.

The chlorine compounds that destroy ozone have now been regulated under the international Montreal Protocol agreement. Because of this agreement, the ozone hole is projected to disappear around 2060-2070. NASA and the international community continue to monitor Antarctic ozone.
