Science Goals for Research on Stratospheric Ozone Depletion and Increased UV Radiation

• Observe and document the trends and patterns of change in ozone concentrations in the Earth's stratosphere and upper troposphere and the related trends and patterns of UV radiation at the Earth's surface.

• Model the physical and chemical processes of the stratosphere and upper troposphere that will allow predictions of ozone change and the resulting change in UV radiation at the Earth's surface.

• Assess the implications of changing ozone concentrations and the resulting changes in UV radiation at the Earth's surface to human health and other life forms.

• Assess the efficacy of the development of new replacement compounds for chlorinated and brominated compounds.
