The Impact of Nonlocal Ammonia on Submicron Particulate Matter and Visibility Degradation in Urban Shanghai
Figure 3
The relationship of particulate species concentration (μg/m3) and visibility (km) (a) PM1, (b) , (c) , and (d) . Data for rain periods and RH > 90% are left out. Data where vis. > 50 km. (upper limit of the instrument) are shown but not used in the calculation.
