Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 percent less ozone
depletion during the Antarctic winter than there was in 2005 - the first year that measurements of chlorine and ozone
during the Antarctic winter were made by NASA's Aura satellite.
