Launch of Air Quality Early Warning System for Delhi and Emission Inventory of Delhi-2018

Hon‘ble Science & Technology, Earth Sciences; Environment, Forest & Climate Change Minister, Dr Harsh Vardhan unveiled an Air Quality Early Warning System for Delhi on 15th October 2018 in New Delhi. The prediction system was developed by scientists of MoES institutions including IITM with the technical support from the National Centre for Atmospheric Research (NCAR) and the Finnish Meteorological Institute (FMI). This 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 Government of India.  During the event, Hon’ble Minister also released the high resolution Emission Inventory for Delhi city and surrounding regions for major pollutants developed by the scientists of IITM. The air pollution system 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 warning system consists of a) 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 b) Predictions of air pollutants from two different air quality prediction systems based on state-of-the-art atmospheric chemistry transport models c) Warning Messages and Alerts and Bulletins.
