Satellite map of ozone levels,northern hemisphere
Numéro d’image : 11736291
| Satellite map showing ozone levels over the Northern Hemisphere on February 21st,1989. The colours represent Dobson Units,a measure of atmospheric ozone. Two areas of low ozone concentration appear in yellow. The smaller region (at 5 o'clock) is located near Baffin Island,Canada and the other,slightly larger feature (at 11 o'clock) is over Siberia. These areas correspond to two lobes of the once stable polar air vortex that became elongated & split. The white area represents polar night,where measure- ments are not possible. Ozone depletion is caused by atmospheric pollution by chloro-fluorocarbons (CFCs) used in aerosols & refrigerants | |
