Caption: Ozone depletion over Antarctica (1997). Coloured satellite map of atmospheric ozone in the southern hemisphere taken on 14th October 1997. An ozone "hole" (dark red) is seen over Antarctica (centre). Ozone levels, measured in Dobson units (DU), are less than 120 DU at the hole, with different colours representing 30 DU steps of increasing atmospheric ozone. Normal atmospheric ozone levels are around 300 DU. Ozone is destroyed by atmospheric pollution. Image created using data from the Total Ozone Vertical Spectrometer (TOVS) on NOAA satellites.
