全国国控站环境空气质量日数据集

该数据集是以国控站点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，可直观反映不同站点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：日数据。
涵盖范围：全国超1600个国控站点。
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 national ambient air quality monitoring sites as the basic unit. It is independently processed in accordance with the requirements of Ambient Air Quality Standards (GB 3095-2012) and its amendment, Technical Regulations on Ambient Air Quality Index (AQI) (for Trial Implementation) (HJ 633-2012), Technical Specifications for Ambient Air Quality Assessment (for Trial Implementation) (HJ 663-2013) and other relevant regulations, forming a comprehensive, systematic and up-to-date collection of air quality information. It can intuitively reflect the air quality conditions of different sites within specific time periods, providing high-quality and computable data support for the modeling and optimization of AI models in scenarios such as environmental prediction, pollution source tracing, and intelligent early warning.
Time Range: 2014 to present (nearly 11 years)
Temporal Resolution: Daily data
Coverage: Over 1,600 national ambient air quality monitoring sites across China
Indicator Parameters: Concentrations of PM2.5, PM10, SO2, NO2, CO, O3, Air Quality Index (AQI), air quality grade, primary pollutant, geographic information (latitude and longitude), etc.
Data Provision Mode: Relevant datasets can be provided by time scale or geographic region, with diverse formats.
