In this study, Beijing, the capital of China, is selected as the study area. Hourly mean concentrations of six regulatory air pollutants including O3 (μg/m3), SO2 (μg/m3), NO2 (μg/m3), PM2.5 (μg/m3), PM10 (μg/m3), and CO (mg/m3) were collected from 35 air quality monitoring stations labeled by 1 to 35 from 01/01/2017 to 05/30/2018. The data was provided by the Ministry of Environmental Protection (MEP) of China. Hourly averaged meteorological data in the same period were first accessed from The National Oceanic and Atmospheric Administration (NOAA), then processed by the Weather Research and Forecasting (WRF) model to produce grid meteorological data (21×31 points) with a grid spacing of 5 km. Meteorological parameters including temperature, air pressure, relative humidity, wind speed, and wind direction are selected as the main meteorological features due to their close relationships with the change of ozone concentrations.
