Satellite map of global ozone on October 2,1987,showing the severe depletion or "hole" in the ozone layer over Antarctica. The hole is probably due to pollution of the atmosphere by chlorofluor- ocarbons (CFCs). First seen in 1980,the "hole" has grown in severity. It reaches a maximum in October,the Antarctic spring. It is visible here as the pink & white area covering the south polar latitudes (bottom). The colours represent Dobson units,a measure of atmospheric ozone; blue,yellow & red represent increasing concentration of ozone. The map was made from data obtained by the Nimbus-7 weather satellite | |
