United States of America

This section describes the contributions of the United States of America to international efforts in atmospheric chemical / dynamical and UV radiation monitoring and research relevant to global changes in atmospheric ozone and its relationship to changes in climate. These research and observational activities provide a set of predictive tools and capabilities that deliver sound scientific information for use by policy and economic decision makers as they consider various options for mitigating or adapting to global change. An attempt has been made to construct a reasonably comprehensive description of the activities supported by the various US Government Agencies that have research programs in these areas, utilizing their FY2002 reports to the US Global Change Research Program (USGCRP) as well as more recent inputs provided specifically for this report. Nevertheless, it is possible that some Agency contributions are not reflected herein.
