Delhi's air quality improves, nears 'moderate' category

The 24-hour average air quality index (AQI) of the city was recorded at 178 by 4 pm, a significant improvement from 268 on Tuesday.

Previously, the AQI had been in the ‘moderate’ category, with a reading of 198 on October 15. However, it worsened to the ‘poor’ category the next day, according to Central Pollution Control Board (CPCB) data.

An official from the India Meteorological Department (IMD) attributed the improved air quality to strong surface winds, which were expected to continue through December 7.
