河北省空气质量日历史数据（2019年）

该数据源来自环保部，数据集由人工整理校对而成，主要应用于大气质量和全球变化研究，本数据库类型为属性数据，该数据集包含河北省2019年每一日的AQI、质量等级、PM2.5、PM10、SO2、CO、NO2、O3_8h等指标数据。其中，AQI：空气质量指数(Air Quality Index)，是定量描述空气质量状况的无量纲指数。PM2.5：细颗粒物又称细粒、细颗粒。参与空气质量评价的大气主要污染物之一。PM10：可吸入颗粒物指空气动力学当量直径≤10微米的颗粒物, 参与空气质量评价的大气主要污染物之一。质量等级：根据空气质量指数（AQI）范围分为六个等级：优：0-50；良：51-100；轻度污染：101-150；中度污染：151-200；重度污染：201-300；严重污染：>300。排名：2014年每一日AQI数值在全国190个城市中的排名。

This data source is derived from the Ministry of Ecology and Environment of the People's Republic of China. The dataset was manually curated and proofread, and is primarily utilized in atmospheric quality and global change research. This database falls into the category of attribute data. The dataset includes daily indicator data for Hebei Province in 2019, covering AQI, air quality grade, PM2.5, PM10, SO2, CO, NO2, O3_8h, and other relevant metrics.

Detailed explanations of the indicators are as follows:
1. AQI (Air Quality Index): A dimensionless index that quantitatively describes the status of air quality.
2. PM2.5: Fine particulate matter (also referred to as fine particles), which is one of the major atmospheric pollutants involved in air quality assessment.
3. PM10: Inhalable particulate matter, defined as particles with an aerodynamic equivalent diameter of ≤10 micrometers, and it is one of the major atmospheric pollutants for air quality evaluation.
4. Air Quality Grade: Divided into six levels based on the AQI range: Excellent (0–50), Good (51–100), Mild Pollution (101–150), Moderate Pollution (151–200), Severe Pollution (201–300), and Serious Pollution (>300).
5. Ranking: The daily AQI values in 2014 were ranked among 190 cities nationwide.
