Meanwhile, data from the CPCB’s Sameer app showed that 22 monitoring stations reported air quality in the ‘severe’ range, while 12 stations recorded ‘very poor’ air quality with readings above 300, as on 10:05 am on Sunday.

Since Diwali, the AQI across Delhi and the National Capital Region (NCR) has hovered in the ‘poor’ and ‘very poor’ ranges, even as Stage II of the Graded Response Action Plan (GRAP) remains in effect. However, authorities have held back on implementing GRAP Stage III, which involves stricter curbs.
