Experiments 11 and 12 were analyzed to investigate the relative importance of these effects.
Figure 4-11 compares the actual and emissions contributions in experiment 12 (without chemical
reactions) at all receptors. Deviations from a 1:1 line in Figure 4-11 show cases where the actual
contributions are not representative of the nearby emissions contributions. The downwind
