Ozone hole over Antarctica Featured 6 Nov 1990 Print

Ozone hole over Antarctica

Satellite map showing a severe depletion or "hole" in the ozone layer over Antarctica on October 3rd, 1990. The hole is believed to be due to pollution of the atmosphere by chlorofluorocarbons used in aerosols & refrigerants. First observed in 1980, the most severe depletion was recorded in October 1987. This image represents the maximum depletion during the Antarctic spring of 1990. It appears here as the violet & pink areas covering Antarctica (outlined in white) & beyond. The scale of colours represents Dobson units, a measure of atmospheric ozone. The map was made by the Total Ozone Mapping Spectrometer (TOMS) on the American Nimbus-7 weather satellite
