On-road black carbon instrument intercomparison and aerosol characteristics by driving environment

The objective of this study was to assess the ability of several high time resolution instruments to capture on-road BC concentrations. An additional objective was to use these measurements to
characterize aerosol characteristics: particle size distribution, BC concentration, and optical properties in a variety of different driving environments. Measurements were made onboard an electric vehicle operated in a variety of traffic environments and vehicle operating conditions including morning and afternoon rush hour, stop-and-go congestion, a heavily traveled intersection, and lightly traveled secondary roads.
