Finally, if 227 there were nucleation mode particles present, resulting in an increase in the ultrafine particle 228 number concentration, but growth was not continuous or sustained, this event was classified as 229 Class C. Due to the 5 nm lower limit in the size distribution data, the growth rates calculated 259 between 5-10 nm were used to estimate the approximate start time of each Class A event. The general start time of all Class A events was 367 also pronounced in the diurnal variation of particle number concentration plots shown in Figure 368 5a.	./cache/cord-355883-uyrn281a.txt	./txt/cord-355883-uyrn281a.txt
