城市环境空气质量小时数据集

该数据集是以城市为基本单位的结构化数据，根据《环境空气质量标准》(GB 3095-2012)及修改单、《环境空气质量指数(AQI)技术规定(试行)》(HJ 633-2012)、《环境空气质量评价技术规范（试行）》（HJ 663-2013）等有关要求，经自主加工后形成全面、系统且具有时效性的空气质量信息汇总，可直观反映不同城市在特定时间段内的空气质量状况，为AI模型在环境预测、污染溯源、智能预警等场景下的建模与优化提供高质量、可计算的数据支撑。 时间范围：2014年至今（近11年） 时间维度：小时数据。 涵盖范围：全国超300个地级及以上城市。 指标参数：PM2.5、PM10、SO2、NO2、CO、O3浓度、空气质量指数（AQI）、空气质量等级、首要污染物、地理信息（经纬度）等。 数据提供方式：可按时间尺度或者按地域提供相关数据集，形式多样。This dataset is structured data with cities as the basic unit. Independently processed in accordance with relevant regulatory requirements including the Ambient Air Quality Standard (GB 3095-2012) and its amendment, the Technical Specifications for Ambient Air Quality Index (AQI) (for Trial Implementation) (HJ 633-2012), and the Technical Specifications for Ambient Air Quality Assessment (for Trial Implementation) (HJ 663-2013), it forms a comprehensive, systematic and up-to-date compilation of air quality information. It can intuitively reflect the air quality conditions of different cities within specific timeframes, and provides high-quality, computable data support for the modeling and optimization of AI models in scenarios such as environmental forecasting, pollution source tracing, and intelligent early warning. Time Range: 2014 to present (nearly 11 years) Temporal Granularity: Hourly data Coverage: Over 300 prefecture-level and above cities across China Indicator Parameters: Concentrations of PM2.5, PM10, SO2, NO2, CO, O3, Air Quality Index (AQI), Air Quality Grade, Primary Pollutant, geographic information (longitude and latitude), etc. Data Provision Method: The relevant dataset can be provided either by time scale or geographic region, with multiple available formats.
