Several years ago spectrophotometer measurements revealed substantial depletions of atmospheric ozone over Antarctica, reviving concerns over damage to Earth's ozone layer by human activities. These ground‐based observations were subsequently verified in global ozone data that had been collected by satellite for years. The sizable ozone depletions over Antarctica are now believed to arise from complex chlorine chemistry, stimulated ultimately by the emission of man‐made chlorofluorocarbons into the atmosphere.
