The average is calculated for January 2018 – March 2019. The details of the particle size distribution measurements and the method used for producing the emissions are presented by Kontkanen et al., Size-resolved particle number emissions in Beijing determined from measured particle size distributions, ACP, 2020. Data file contents: 1st row contains particle diameter (unit:m). 1st column contains time (unit:hour), and the following columns contain particle number emissions (unit: m-2 s-1).
