New Delhi, Dec 26 The national capital witnessed a marginal improvement in air quality on Friday, with the Air Quality Index (AQI) falling into the ‘poor’ category and averaging 292, according to official data.
The improvement comes after Delhi recorded ‘severe’ air quality levels earlier this week, with the AQI touching 412 on December 23. Over the past two days, a gradual decline in pollution levels has been observed across several parts of the city.
Data from the Central Pollution Control Board’s (CPCB) Sameer mobile application showed that, as of 6.05 a.m., three monitoring stations reported air quality in the ‘moderate’ category. These included Lodhi Road-IITM with an AQI of 160, Lodhi Road-IMD at 194, and Najafgarh at 188.
Several other stations recorded AQI levels in the ‘poor’ category. These included Aya Nagar (212), CRRI Mathura Road (265), Dr Karni Singh Shooting Range (290), Dwarka Sector 8 (282), IGI Airport Terminal 3 (238), IIT Delhi (231), Jawaharlal Nehru Stadium (253), and Mandir Marg (222), among others.

In view of the recent improvement in air quality, the Commission for Air Quality Management (CAQM) lifted the Graded Response Action Plan (GRAP) Stage-IV restrictions across the Delhi-National Capital Region (NCR) on December 24. Officials said that if the improving trend continues, further relaxations in pollution control measures could be considered in the coming days.
