Abstract

PM2.5 in air usually contains a large amount of toxic and harmful substances and has a long residence time and transport distance in the atmosphere. [...]it has become a great burden on human health [2,3,4]. [...]PM2.5 and O3 have different relationships in different regions and during different time periods. [31] indicated that a more important factor for ozone trends in the North China Plain is the ∼40% decrease of PM2.5 over the 2013–2017 period, which slow down the aerosol sink of hydroperoxy (HO2) radicals and thus stimulate ozone production. [...]to obtain a systematical and explicit relationship between PM2.5 and O3 which is not limited to a certain area, it is necessary to describe the spatial-temporal characteristics of R-PO in detail. The data source of this study was the “National Urban Air Quality Real-time Publishing Platform” (http://106.37.208.233:20035/). Since there are a few abnormalities in the raw observation data, the hourly PM2.5 and O3 monitoring data were preprocessed.
