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.
