Figures & data
FIG. 1. Ten minute averaged black carbon (BC) and particle number (PN) concentrations from water-based (W-CPC) particle concentrations on the weekday (a) and only averaged BC concentrations on the weekend (b).
FIG. 2. The weekday particle size and number distributions measured with a (a) B-CPC and (b) W-CPC. The weekend particle size and number distributions measured with a (c) B-CPC and (d) W-CPC. The scale between the figures shows particle number concentration (# cm−3).
FIG. 3. The comparison of water to butanol particle concentration counts (ratio from 0 to 1) for the (a) weekday and (b) weekend measurements.
FIG. 4. Changing κ (dashed line) and ϵ50 (solid line) for both weekday and weekend data sets. The shaded region represents the time before the wind change.
FIG. 5. Black carbon concentration versus inferred water insoluble mass from the weekday (a) and weekend (b) measurements. The solid line shows the rate of increase; either 1:1 for the weekday and 2:1 for weekend. Dashed lines represent 25% deviation from (a) 1:1 or (b) 2:1 solid lines.
