Dataset: Air Quality Dataset for Chengdu (2022-08-01 to 2026-02-18)

This dataset contains historical air quality time series for Chengdu covering 2022-08-01 to 2026-02-18. It includes key air pollution indicators such as AQI indices and major pollutants, plus city metadata including coordinates, administrative areas, and population. Use this dataset to analyze long-run air quality trends in Chengdu, compare Chengdu with other cities, and build models that link air quality to urban characteristics. Air quality values are retrieved from the Open-Meteo Air Quality service using the cams_global domain, and city metadata is derived from the GeoNames city list. Nitiraj Kulkarni本数据集收录成都地区2022年8月1日至2026年2月18日的历史空气质量时序数据，包含空气质量指数（AQI）、主要污染物等核心空气污染监测指标，同时附带城市元数据，涵盖地理坐标、行政区划与人口信息。本数据集可用于分析成都长期空气质量变化趋势、开展成都与其他城市的空气质量对比研究，以及构建关联空气质量与城市特征的分析模型。空气质量数据通过Open-Meteo空气质量服务的cams_global数据集域获取，城市元数据源自GeoNames城市名录。Nitiraj Kulkarni
