Delhi experienced a minor improvement in its air quality on Wednesday morning, with pollution levels declining marginally and the Air Quality Index (AQI) moving closer to the 'poor' category. According to the Central Pollution Control Board (CPCB), the city recorded an AQI of 301 at 9 am, compared to a more alarming 343 at the same time on Tuesday. Despite the slight improvement, a thick haze continued to envelop the national capital.

The CPCB categorises AQI values between zero and 50 as 'good', 51 to 100 as 'satisfactory', 101 to 200 as 'moderate', 201 to 300 as 'poor', 301 to 400 as 'very poor', and 401 to 500 as 'severe'. According to the data, none of Delhi’s 38 active monitoring stations reported air quality in the 'severe' category on Wednesday. This marks a positive shift, as on Tuesday, 17 of the capital's 39 monitoring stations recorded air quality in the 'severe' range.
