Air quality data for 328 cities across China from 2013 to 2022

This dataset is derived from China's meteorological historical data, covering the national geographical scope, with historical data updated to 2022. The core indicators include six types of atmospheric pollutants: PM2.5, PM10, sulfur dioxide (SO₂), nitrogen dioxide (NO₂), ozone (O₃), and carbon monoxide (CO). The dataset records the historical monitoring information of the above pollutants nationwide, which can be used to analyze the long-term spatiotemporal evolution law of atmospheric pollution and regional pollution characteristics, providing data support for atmospheric pollution control research and environmental management decisions.
