According to the CPCB's Sameer app, 16 out of the 40 monitoring stations in the city reported air quality in the 'severe' category, while the remaining recorded 'very poor' levels.
An AQI between 0 and 50 is considered 'good', 51 to 100 'satisfactory', 101 to 200 'moderate', 201 to 300 'poor', 301 to 400 'very poor', and 401 to 500 'severe', according to the CPCB classification.

The visibility improved to 600 metres in shallow fog but fell back to 350 metres, with east-southeasterly winds blowing at a speed of 7 kilometres per hour, it said.
At Safdarjung, the visibility dropped to its lowest at 200 metres in moderate fog between 1.30 am and 2.30 am IST. It gradually improved to 500 metres in shallow fog by 5.30 am, the IMD said.

A new study published in Science has challenged this view, suggesting the genetic contribution might be considerably higher.
Several parts of the national capital woke up to dense fog on Monday morning, with the Air Quality Index (AQI) remaining in the moderate to poor categories according to the Central Pollution Control Board (CPCB) data.
India's fight against toxic air just took a hit. The 2026-27 Budget allocated only Rs 1,091 crore to pollution control - down from Rs 1,300 crore last year.
Several parts of Delhi and the wider National Capital Region (NCR) witnessed light rain during the intervening night of Saturday and Sunday. The India Meteorological Department (IMD) has forecast a drop in the maximum temperature for today.
The air quality in Delhi has shown slight deterioration this January compared to last year, with the average Air Quality Index (AQI) till January 30 standing at 307, compared to 306 during the same period in 2025, according to an analysis
