Why in News?

Air Quality Early Warning System for Delhi was launched in Delhi by the Union Environment Minister Harshvardhan.The Environment Minister said that with the early information on bad air quality, people can be educated to get well prepared in advance.

Air Quality Index

*An Air Quality Index in the range of 0-50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’ and 401-500 ‘severe’.
*The Supreme Court has empowered the Environment Pollution Control Authority(EPCA) to take various measures to tackle pollution. Under the order, the EPCA has mandated enforcement of Graded Response Action Plan (GRAP) in the city.

Key Highlights 

*It has been developed jointly by the scientists at Indian Institute of Tropical Meteorology (IITM), Pune, India Meteorological Department and National Centre for Medium Range Weather Forecasting (NCMRWF).
*The System is designed to predict extreme air pollution events and give alerts to take necessary steps as per Graded Response Action Plan (GRAP) of the Govt. of India.Such information may be helpful for the general public in planning their outdoor activities.
*The system will also make it easier for government’s pollution watchdogs to alert stakeholders and the general public about air quality 48 hours in advance.
*The warning system consists of
  • real time observations of air quality over Delhi region and details about natural aerosols like dust (from dust storms) and particulate matter using different satellite data sets
  • Predictions of air pollutants from two different air quality prediction systems based on state-of-the-art atmospheric chemistry transport models and
  • Warning Messages and Alerts and Bulletins

Measures to prevent

*As per the Union Government, the Central Pollution Control Board (CPBC) is proactively doing examination in bordering regions and sending reports of influenced spots to the concerned division. The Government is likewise finding a way to diminish emission from vehicles.
*MoES has made endeavors to enhance precision of expectations models with the specialized help from the NCAR, USA and Finnish Meteorological Institute.
*The Delhi Government likewise revealed its emergency action plan - Graded Response Action Plan (GRAP) for the second year in succession on October 15.
* The plan, which was first actualized in 2017, plans to battle 'extremely poor' and 'serious' air pollution level.
* Under the emergency action plan, stringent measures will be actualized, for example, a prohibition on diesel generator (DG) sets in Delhi.
* If the air quality crumbles further and comes to the 'extreme' or 'crisis' classifications, other stringent measures including the restriction on construction exercises, prohibition on stone crushers and hot mix plants, upgrading stopping charges and revealing the odd-even street rationing scheme will be executed.
*The measures recorded under GRAP to control 'moderate' and 'poor' levels of pollution are for the most part implemented in the summer and monsoon months and measures to control ‘very poor’ and ‘severe’ categories of pollution will be upheld from October 15 to March 15 of the next year.
