英文摘要:
Emissions from vehicles are a major source of volatile organic compounds in urban environments. Diesel exhaust profile measured by the PTR-ToF instrument was compared to the diesel exhaust speciation profile currently used by the European Environemnt Agency and the US EPA for emission inventories. The US EPA exhaust profile, SPECIATE #8775, was currently used in the Motor Vehicle Emissions Simulator 2014 model and similar diesel exhaust source profile have been used in compiling the National Emissions Inventory used of air quality modeling in the US. There is also a compelling field experiment opportunity to guide emission inventory development in concert with photochemical modeling development by contrasting ozone and organic PM formation in European cities dominated by diesel vehicle emissions to US cities dominated by gasoline vehicle emissions.
