Air quality index India

National Air quality index (AQI) India: 

  • Launched by – MoEF in 2015.
  • Initiative under ‘Swachh Bharat’.
  • It helps the common man to judge the air quality within his vicinity.
  • Index constituted as a part of the Government’s mission to improve the culture of
    cleanliness.
  • Central Pollution Control Board (CPCB) along with State Pollution Control Boards has
    been operating the National Air Monitoring Program (NAMP).
  • Developed by – IIT Kanpur.
  • While the earlier measuring index was limited to 3 indicators, the current measurement index had been made quite comprehensive by the addition of 5 additional parameters.

Need of AQI

  • Quality of data from some cities remains weak and the standards set for pollutants fall short of WHO recommendations.
  • The pollution related analysis using a vast number of complex parameters is complicated for the common man to understand.
Categories of air pollution under AQI
  • There are six AQI categories, namely Good, Satisfactory, Moderately polluted, Poor,
    Very Poor, and Severe.
