1996 Antarctic ozone hole below record average size
News story originally written on October 25, 1996

One of NASA's measuring instruments aboard a satellite has detected large decreases of ozone over Antarctica. Ozone is a chemical that forms in a layer in the Earth's atmosphere. Ozone protects our Earth from dangerous solar radiation.

There has been a large ozone hole over Antarctica over the past three years. This year, the ozone hole has increased, though the actual amount of ozone has increased slightly over the past two years.

The average size of the ozone hole during this year was 8.3 million square miles. The largest observed size of the ozone hole was in 1993, at 8.5 million square miles.
