Hourly surface ozone observations across China

Historical monitoring data of air quality sites across China (2014-2022) obtained by the China National Environmental Monitoring Center (CNEMC; https://air.cnemc.cn:18007/). The file named Station_information.csv contains details about the stations, including the city location, latitude, longitude, and elevation (m). The ozone.zip file encompasses ozone concentration data from 2014 to 2022, featuring columns for date, hour, and surface ozone concentrations at each station code(ug/m3; Beijing time: UTC+8:00). Further information about the data is available from scholar Xiaolei Wang, who also offers additional data for download on his personal webpage (https://quotsoft.net/air/).
