After Diwali celebrations, air quality in the Delhi and National Capital Region (NCR) saw a sharp dip and gradually deteriorated as stubble burning continues in parts of Punjab and Haryana despite a ban. According to the Air Quality and Weather Forecasting and Research System (SAFAR), Delhi’s overall air quality has deteriorated to 425, which is classified as “severe.” 

All pollution measuring stations in Delhi-NCR, like Anand Vihar (478), Alipur (473), Aya Nagar (430), Dwarka (447), Major Dhyanchand Stadium (445) and Patparganj (443), record AQI levels above 400. Data show that the sudden sharp dip in air quality was seen after Diwali celebrations. Today, the level of haze covering the national capital and surrounding regions appears to have jumped. For the fourth consecutive day, as more than 20 of the 37 AQI monitoring stations across Delhi recorded severe air quality levels, the city is expected to remain blanketed under the pungent haze. Data from the air quality monitoring system of the Ministry of Earth Sciences, SAFAR, showed that the share of stubble burning is the main reason for the toxic haze in and around New Delhi.

Weather experts are of the opinion that increased wind speed due to fresh western disturbance would help to disperse pollutants faster from Saturday.
