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/). Station_information.csv file provides information about the city of the station, as well as latitude and longitude. In the YYYYMMDD_CNEMC.zip files, the first row is the column names, which are the date, hour, data type, and code for each monitoring point; each of the following rows is for one type of data at a particular moment in time. More information about the data comes from scholar Xiaolei Wang, who has also made other data information available for download on his personal webpage (https://quotsoft.net/air/).
