Day wise, State wise Air Quality Index (AQI) of Major Cities and Towns in India

The datasets contains date- and state-wise historically compiled data on air quality (by pollution level) in rural and urban areas of India from the year 2015 , as measured by Central Pollution Board (CPCB) through its daily (24 hourly measurements, taken at 4 PM everyday) Air Quality Index (AQI) reports.

The CPCB measures air quality by continuous online monitoring of various pollutants such as Particulate Matter10 (PM10), Particulate Matter2.5 (PM2.5), Sulphur Dioxide (SO2), Nitrogen Oxide or Oxides of Nitrogen (NO2), Ozone (O3), Carbon Monoxide (CO), Ammonic (NH3) and Lead (Pb) and calculating their level of pollution in the ambient air. Based on the each pollutant load in the air and their associated health impacts, the CPCB calculates the overall Air Pollution in Air Quality Index (AQI) value and publishes the data. This AQI data is then used by CPCB to report the air quality status i.e good, satisfactory, moderate, poor, very poor and severe, etc. of a particular location and their related health impacts because of air pollution.

本数据集收录了2015年起印度城乡地区按日期与邦级行政单位分类的历史空气质量（按污染水平划分）汇编数据，数据由中央污染控制委员会（Central Pollution Board, CPCB）通过其每日空气质量指数（Air Quality Index, AQI）报告获取，该报告每日下午4点采集24小时监测数据。
中央污染控制委员会通过对多种污染物开展连续在线监测以评估空气质量，监测对象包括可吸入颗粒物10（PM10）、细颗粒物2.5（PM2.5）、二氧化硫（SO2）、二氧化氮（NO2）、臭氧（O3）、一氧化碳（CO）、氨（NH3）与铅（Pb），并计算这些污染物在环境空气中的污染水平。基于空气中各污染物的负荷量及其对应的健康影响，中央污染控制委员会将计算得出综合空气质量指数（AQI）值并发布相关数据。该AQI数据随后被用于报告特定区域的空气质量状况，涵盖优、良好、中等、较差、极差、严重等等级，以及由空气污染引发的相关健康影响。
