The Antarctic ozone hole, as measured by NOAA’s Solar Backscatter Ultraviolet (SBUV) instrument, during October 2006.
Normal values of ozone are close to 300 Dobson Units, as shown by the blue areas at the tropical latitudes of the southern hemisphere. Over Antarctica, values are as low as 100 to 120 Dobson units. That means more than half of the Antarctic ozone is destroyed each spring as a result of the presence of the remaining human-produced CFCs that entered the atmosphere prior to the 1980s.See "Environmental satellites: Innovation in action", by George Ohring (NOAA) OECD Observer No. 261, May 2007
