OSTI ID:5702593

A review is presented of the current understanding of stratospheric ozone (SO). The focus is on four major current aspects of SO: (1) polar ozone; (2) global trends; (3) theoretical predictions; and (4) halocarbon ozone depleting materials and global warming potentials. Other ozone related topics are also discussed: (1) the trends of stratospheric temperature, stratospheric aerosols, source gases, and surface ultraviolet radiation; and (2) the oxidizing capacity of the troposphere as it pertains to the lifetimes of ozone related chemicals. There have been highly significant advances in the understanding of the impact of human activities on the Earth's protective ozone layer. There are four major findings that each heighten the concern that chlorine and bromine containing chemicals can lead to a significant depletion of SO: (1) Antarctic Ozone Hole; (2) Perturbed Arctic Chemistry; (3) Long-term Ozone Decreases; and (4) Model Limitations.
