Continued decline of total ozone over Halley, Antarctica, since 1985
IN 1985, Farman et al.1 announced that a dramatic reduction in total ozone was occurring in the atmosphere over Halley, Antarctica, during the polar spring. Analysis of satellite data revealed that this ozone depletion was an Antarctic-wide phenomenon2. Combined theoretical3á¤-5, observational6,7 an...
