Title

Annual Average Vs Monthly Average Values For Selected Inputs To Mobile6 - Effect On An Annual Emissions Inventory

Abstract

In many urban areas, on-road vehicles are the biggest contributing source category of VOCs and NO x. Based on a recently completed emission inventory study for three counties in Central Florida, the major source by far of anthropogenic VOCs and NO x was on-road mobile sources, even though other sources (such as construction equipment, lawn and garden equipment, and various point sources) were also significant. Although there is specific guidance for conducting an ozone-season inventory for mobile sources, there is a lack of detailed guidance as to how to employ EPA's latest mobile source emission factor program, MOBILE6, for an annual inventory. Several of the MOBILE6 inputs that significantly influence emission factors (e.g., temperature) can vary widely throughout the year, and the annual average value may not be appropriate. Rather it may be better to utilize monthly values of these parameters. This paper investigates the sensitivity of the annual emission inventory results to using annual or monthly values of temperature, RVP of gasoline, and humidity.
