Comparison of performance of several photochemical models

Conference ·
OSTI ID:20002106

There are several photochemical models that states may use for State Implementation Plan (SIP) development. The Urban Airshed Model (UAM) version IV is the photochemical model that is recommended for use in SIP development in the US Environmental Protection Agency's (EPA's), Guideline for Air Quality Modeling. Other models may be used if demonstrated to be appropriate. In the past, Texas has used the UAM-IV for SIP development. However, the latest SIPs have been prepared with the Comprehensive Air Quality Model with Extensions (CAMx). This paper provides a comparison of the performance of the CAMx, UAM-IV and UAM version V using the Coastal Oxidants Assessment for Southeast (COAST) data base. The COAST data is a comprehensive set of monitoring and emissions inventory data collected in 1993. Results of an extensive set of performance evaluation tests and other statistics will be included in the paper.
