河南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，该数据集包含河南省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 originates from the Ministry of Environmental Protection. The dataset was manually curated and proofread, and is primarily utilized for air quality and global change research. This database falls into the category of attribute data. This dataset contains daily indicator data for Henan Province in 2019, including AQI, air quality grade, PM2.5, PM10, SO2, CO, NO2, O3_8h and other related indicators. Detailed explanations of each indicator are as follows: 1. AQI (Air Quality Index): A dimensionless index for quantitatively describing air quality status. 2. PM2.5: Fine particulate matter, also referred to as fine particles, is one of the major atmospheric pollutants involved in air quality evaluation. 3. PM10: Inhalable particulate matter refers to particulate matter with an aerodynamic equivalent diameter of ≤10 μm, and it is one of the major atmospheric pollutants involved in air quality evaluation. 4. Air quality grade: Divided into six levels based on the range of Air Quality Index (AQI): Excellent (0-50), Good (51-100), Lightly Polluted (101-150), Moderately Polluted (151-200), Heavily Polluted (201-300), Severely Polluted (>300). 5. Ranking: The daily AQI values in 2014 were ranked among 190 cities nationwide.
