Fig. 18: The evolution of particle formation rate as a function of nanoparticle ranking.
From: Understanding atmospheric processes: insights from the comparison between Beijing and Hyytiälä

The particle formation rate (J3) in both Beijing (red) and Hyytiälä (blue) are shown. Within each box, the median (middle horizontal line), mean (solid circles), 25 and 75 percentiles (lower and upper ends of the box), and 10 and 90 percentiles (lower and upper whiskers) are shown. Line with black cycles are the ratios of J3 between Beijing and Hyytiälä. Hourly mean datasets within the NPF active time window (10:00 to 14:00) were used, covering the period from 2018 to 2022 in Hyytiälä and the period from 2018 to 2020 in Beijing.
