ABSTRACT
In 1997, the Antarctic ozone hole was one of the largest, and was no different from the holes of other years of the past decade. For nearly three months, the surface of the ozone hole remained constantly larger than a square area of 10 million km2. In September and October it nearly doubled and reached its peak at around 24 million km2.1 Also, there was ozone depletion in the lower stratosphere, which added to the overall dimensions of the ozone hole, which extended in 1998 to the southernmost tip of South America.2
