This dataset compiles concentrations of PM2.5 (μg/m3), PM10 (μg/m3), SO2 (ppb), CO (ppm), NO2 (ppb), and O3 measured by general automatic air quality monitoring stations set up by the Ministry of Environmental Protection nationwide and by county/city; and compiles the TSP (μg/m3) reported by local monitoring stations set up by local environmental protection agencies. Except for O3 values, which are calculated as the arithmetic mean of the maximum effective hourly values ​​for each day, all other pollutant values ​​are averages.
