The purpose of the process research breakout session is to define collaborative research projects that will increase the understanding of the chemical, meteorological and depositional processes that determine air-quality. Also, implied in this discussion is the independent evaluation of emission inventories that is based on inconsistencies between our current understanding of these processes and our measurements of ambient concentrations and deposition loadings. The breakout session consists of scientists from each agency who provided a series of short presentations outlining current and planned future process research in chemistry, meteorology and deposition. The presentations covered the following information concerning future research projects:
- Scientific issue addressed
- Research approach and time-line
- New opportunities afforded by advances in measurement and/or process modeling technologies
- An indication of how the proposed research will increase understanding and lead to improved air-quality management

Following the presentations, 30 minutes was devoted to a question and answer period for further clarification of the presentations and to identify potential important gaps in process research that were not described in the presentations. The remaining 90 minutes was spent discussing the collaborative research projects that may be undertaken within the framework of existing agency programs or beyond the completion dates for these programs. These projects make best use of the considerable scientific strengths and resources of the two agencies. Process research topics include: (1) theoretical studies and laboratory experiments for developing process models for air quality models and (2) field studies and/or testbed approaches using state of the science chemistry and meteorological methods to develop and/or evaluate process or emission components of air quality models. These discussions provide a list of relevant collaborative atmospheric process research projects that can significantly improve our understanding of source-receptor relationships and their application to guide air-quality management.
