Abstract

A series of Urban Airshed Model (UAM) sensitivity studies were conducted using two summer ozone episodes. Plausible alternative conditions were established to define acceptable base cases, some of which provided model performance comparable to the best achieved for the episodes. The alternative base cases used in this study produced significant differences in estimates of the air quality benefits of hypothetical emissions reduction. The study strongly recommends that current photochemical modeling practice include this type of analysis to reduce the risk of focusing on the wrong ozone precursor, underestimating control requirements, or incurring costs to implement unnecessary controls.
