Numéro d’image : 11736292
| Satellite map showing a severe depletion or "hole" in the ozone layer over Antarctica on October 5th,1987. The hole is probably due to pollution of the atmosphere by chlorofluorocarbons used in aerosols & refrigerants. First seen in 1980,the hole has grown each year since. It reaches a maximum in October,the Antarctic spring. It is visible here as the deep blue,purple,black & pink area 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 | |
