Caption: Satellite map showing a severe depletion or "hole" in the ozone layer over Antarctica on October 5th, 1989. The hole is probably 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. It reaches a maximum in October, the Antarctic spring. It is visible here as the pink and purple areas covering Antarctica (outlined in white) & beyond. The colours represent Dobson units, a measure of atmospheric ozone, as shown in the colour scale at right. The map was made by the Total Ozone Mapping Spectrometer (TOMS) on the American Nimbus-7 weather satellite.
