Development and application of an up-to-date photochemical mechanism for airshed modeling and reactivity assessment. Final report
The major focus of this project was the development of the Maximum Incremental Reactivity (MIR) scale which was implemented in the ARB`s Clean Fuels/Low-Emissions Vehicle regulations as a means to calculate ozone reactivity adjustment factors (RAF`s) so that volatile organic compound (VOC) emissions from different fuel/vehicle combinations can be regulated on an equal ozone impact basis. The main body of this report documents the development of the MIR and other reactivity scales, and discusses how best to develop an optimum scale for ozone reactivity assessment for VOCs. It is concluded that the MIR scale gives similar RAFs as a scale based on effects of VOCs on integrated ozone, and that either type of scale is appropriate for applications requiring use of a single reactivity scale.
