Guidance for the Performance Evaluation of Three-Dimensional Air Quality Modeling Systems for Particulate Matter and Visibility

Abstract: The National Ambient Air Quality Standards for particulate matter (PM) and the federal regional haze regulations place some emphasis on the assessment of fine particle (PM; 5) concentrations. Current air quality models need to be improved and evaluated against observations to assess the reliability of model simulations. The guidance presented here provides the necessary framework for conducting rigorous performance evaluations of PM and visibility models. The costs associated with the Field programs needed to obtain the data necessary for such performance evaluations are estimated to be $15 million for data collection (1 -year program with an intensive program of 15 days, over 200,000 km2) and $10-$20 million for planning, emission inventories, data analysis, and modeling.

The U.S. Environmental Protection Agency (EPA), through its Office of Research and Development, colloborated in the research described here. It has been subjected to EPA review and approved for publication. Mention of trade names of commercial products does not constitute an endorsement or recommendation for use.
