Particulate matter sources on an hourly timescale in a rural community during the winter

Figures & data

Figure 1. Average hourly PM₁₀ concentrations at (a) the Bowling Club, Girl Guides, and Central Otago District Council office sites and (b) at the Girl Guides and Aloft sites during periods when the knuckleboom was raised.

Figure 2. Source profiles obtained at the Alexandra Girl Guides site.

Figure 3. Average hourly source contributions at the Alexandra Girl Guides site.

Figure 4. Polar plots of biomass combustion contributions during the night (a) and day (b) at the GG site. The radial dimensions indicate the wind speed in 1-msec⁻¹ increments and the color contours indicate the average contribution to each wind direction/speed bin.
