In the 2002 Ozone Assessment, the international scientific community included this section to answer several of the general questions that are most frequently asked by students, the general public, and leaders in industry and government. A draft of this component was reviewed and discussed by the 74 scientists who attended the Panel Review Meeting for the 2002 report in June 2002. In addition, subsequent contributions, reviews, or comments were made by individuals listed on the inside cover .
Individual components, including each question and associated figures:
