CMAS Exit, in collaboration with EPA scientists, has organized periodic CMAQ review panel meetings, of 3-day duration each. The review process usually starts by inviting a number of key scientists to participate in the process. The scientists are selected based on their expertise in accordance with the focus of the review session. After reviewing numerous reports and articles and completing their meeting in Research Triangle Park, North Carolina, the review panel prepares a comprehensive report on their findings and recommendations. EPA then responds to the comments of the reviewers. Final review reports are posted below.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
