The national capital witnessed the season’s highest contribution of pollutants from farm fires which accounts to 40 per cent on October 1, Sunday. As per the data from Centre’s System of Air Quality and Weather Forecasting and Research (SAFAR), on the weekend, Delhi’s air quality index (AQI) stood at the higher end of the ‘very poor’ category owing to emissions from stubble burning in the neighbouring states of Punjab, Haryana, Uttar Pradesh and Uttarakhand.
According to the Sunday bulletin from SAFAR, “In spite of improved wind conditions, air quality has not progressed as expected due to high stubble-related intrusion and trapping of pollutants during night time due to low wintertime boundary layer height.”
