Background Image: Caption: A NASA instrument — called TOMS (Total Ozone Mapping Spectrometer) — records ozone depletion above Antarctica. Commonly called the "antarctic ozone hole," the depleted area is three times larger than the entire land mass of the United States — the largest such area ever observed. The "hole" expanded to a record size of approximately 11 million square miles (28.3 million square kilometers) on 3 September 2000. The previous record was approximately 10.5 million square miles (27.2 million square km) on 19 September 1998. The lowest readings in the ozone hole are typically observed in late September or early October each year.
