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/).

本研究的目标为，利用中国地表逐小时臭氧观测数据，识别国内高温环境下的臭氧抑制现象，并评估臭氧抑制效应的未来变化趋势。本数据集包含空气质量指数（Air Quality Index，AQI）、PM2.5、PM10、SO2、NO2及CO的逐小时、24小时平均浓度数据，以及臭氧（O3）浓度的逐小时、日最大8小时平均浓度及日最大浓度数据。本数据集的时间跨度为2015年至2019年，数据来源于中华人民共和国生态环境部（http://www.cnemc.cn/en/）。
