Delhi-NCR saw a slight improvement in air quality and visibility on Tuesday as north-westerly surface winds helped disperse the dense fog that had blanketed the region on Monday. The improvement brought limited relief to residents after several days of choking pollution. However, authorities cautioned that disruptions to flight operations at the Delhi airport were likely to continue, even as conditions gradually recovered.
According to data from the Central Pollution Control Board’s (CPCB) Sameer app, Delhi’s air quality index (AQI) stood at 381 at around 6:30 am on Tuesday. This placed the city in the ‘very poor’ category, a noticeable decline from Monday’s average AQI of 427, which marked the third consecutive day of ‘severe’ pollution levels in the national capital.
