Ozone depletion over Antarctica. Coloured three- dimensional (3-D) image of atmospheric ozone depletion over Antarctica. The ozone hole (blue, centre) is seen with the outline of Antarctica and South America. The ozone hole reached a record size in September 1998. Ozone concentrations run from red (highest) through yellow and green to blue (lowest). The ozone hole, mainly caused by atmospheric chlorofluorocarbon (CFC) pollution, is largest around October, the Antarctic spring. Ozone shields the Earth's surface from the Sun's harmful ultraviolet radiation. This image was made using satellite mapping spectrometer data.
