External Review of the CMAQ System

Panels of U.S. and international experts in atmospheric science are convened periodically to peer review new CMAQ versions.  The panel’s findings are released to the public along with the software to promote the software’s sound scientific use.  Members of the peer review panel are selected based on their expertise in accordance with the focus of the review session.  After reviewing numerous reports and articles and completing their three-day meeting in Research Triangle Park, N.C., 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.
