Ozone data appendix to the manuscript: Suppression of Ozone Formation at High Temperature in China: From Historical Observations to Future Projections

The objectives of our study are to identify the suppression of ozone at high temperature in China by using surface hourly ozone data, and to assess the future changes in ozone suppression. This dataset contains the hourly, 24 hours average values of Air Quality Index (AQI), PM2.5, PM10, SO2, NO2, and CO, and the hourly, the daily maximum 8 hours average, and the daily maximum values of O3 concentrations. The dataset coverages the period of 2015 to 2019 and is collected from the Ministry of Ecology and Environment of the People’s Republic of China (http://www.cnemc.cn/en/).
