全国国控站环境空气质量小时数据集

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：小时数据。
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-level air quality monitoring stations as the basic unit. Processed independently in accordance with the requirements of relevant standards including Ambient Air Quality Standard (GB 3095-2012) and its amendment, Technical Regulation on Ambient Air Quality Index (AQI) (HJ 633-2012, for trial implementation), and Technical Specification for Ambient Air Quality Assessment (HJ 663-2013, for trial implementation), it constitutes a comprehensive, systematic and timely summary of air quality information. This dataset can directly reflect the air quality conditions of various stations during specific time periods, and provides high-quality, 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: From 2014 to the present (nearly 11 years)
Temporal Granularity: Hourly data
Coverage: Over 1,600 national-level air quality monitoring stations across China
Indicator Parameters: Concentrations of PM2.5, PM10, SO2, NO2, CO and O3, Air Quality Index (AQI), air quality grade, primary pollutant, geographic information (latitude and longitude), and other related indicators
Data Provision Method: Relevant datasets can be provided either by time scale or geographic region, with diverse formats.
