The U.S. Environmental Protection Agency (EPA) and the Organization for Economic Cooperation and Development (OECD) are concerned (1) by the fact that the photochemical oxidant pollution problem, due to large-scale formation or long-range atmospheric transport, has international dimensions, and (2) by the lack of ready-to-use methods for formulating optimum control strategies for regional oxidant reduction. In reaction to these concerns, the U.S. EPA and OECD jointly organized the international conference documented in these proceedings. These proceedings contain presentations made at the conference by some of the world's foremost experts in the field of oxidant air quality modeling and presentations made by national experts on their countries' emissions inventories and air quality monitoring activities. Also included are discussions of the presentations, informal presentations, panel discussions, and conference conclusions and recommendations. Among the subjects discussed were the need for and utility of regional oxidant models, six regional models currently under development, and available aerometric and emissions inventory data bases in OECD countries.
