Abstract

Motor vehicles are one of the largest emitters of ground-level ozone precursors – volatile organic compounds (VOCs) and nitrogen oxides (NO1) – into the atmosphere. Consequently, the Clean Air Act Amendment of 1990 requires the implementation of transportation control measures in order to reduce ground-level ozone precursor emissions and alleviate the ozone air quality problems. This research investigates the relative effects of motor vehicle emissions of VOCs and NO1 on hourly average concentrations of ground level ozone in the Indiana Airshed Model (UAM-IV). The findings of the research study are presented. This includes the results of the data analyses leading to the modeling domain definition, episodes selection, and the different UAM-IV performance evaluation and the sensitivity analyses on VOCs and NO1 emission reductions.
