摘要：	Emission inventories are used to assess the effectiveness of emission programs and to model the formation of secondary pollutants (e.g., ozone) whose concentrations are not directly proportional to the emission of precursors leading to its formation in the atmosphere. These inventories are currently based on average weekday emissions during the summer or winter. However, emissions also vary by day of week and time of day. These variations have ambient air quality implications. Proper characterization of the temporal, spatial, and compositional variations in emissions is important for the development of cost-effective and health-protective emission control regulations for criteria pollutants and toxic air contaminants. The purpose of this project was to collect and characterize pertinent activity data in the South Coast Air Basin (So CAB) that could be used for improving current estimates of the temporal variations in emissions from important source categories. More accurate characterization of emissions will lead to more accurate modeling of air quality impacts and to more cost-effective and health-protective emission control regulations.
