2013年-2022年全国328个城市的空气质量数据

本数据集来源于中国气象历史数据，覆盖全国地域范围，历史数据更新至 2022 年，核心指标包含 PM2.5、PM10、二氧化硫（SO₂）、二氧化氮（NO₂）、臭氧（O₃）、一氧化碳（CO）六类大气污染物。数据集记录了全国范围内上述污染物的历史监测信息，可用于分析大气污染的长期时空演变规律、区域污染特征，为大气污染治理研究及环境管理决策提供数据支持

This dataset is derived from historical meteorological data across China, covering the entire national territory, with all historical records updated to 2022. Its 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 documents historical monitoring information of the aforementioned pollutants nationwide, which can be used to analyze the long-term spatiotemporal evolution patterns and regional pollution characteristics of air pollution, and provide data support for air pollution control research and environmental management decision-making.
