Short summary
We present an approach to track separate contributions to PM2.5 by gasoline and diesel vehicles through a positive matrix factorization analysis of online monitoring data measurable by relatively inexpensive analytical instruments. They are PM2.5 organic and elemental carbon, C2–C9 volatile organic compounds, and nitrogen oxide concentrations. The method was demonstrated to be effective by applying monitoring data spanning 6 years (2011–2017) from a roadside environment in Hong Kong.
