Delhi air quality deteriorates to very poor after morning improvement

Delhi's air quality worsened on Saturday, dropping back into the "very poor" category with a 24-hour average Air Quality Index (AQI) of 316, up from 290 in the morning. Anand Vihar recorded "severe" levels above 400. Most monitoring stations in the city reported AQI levels above 300, while nearby Ghaziabad also fell into the "very poor" category at 330. In contrast, Gurugram, Greater Noida, and Noida had better air quality, classified as "poor." Despite a ban on firecrackers during Diwali, Delhi's air quality did not reach "severe" levels due to favorable winds. The weather forecast predicts mist on Sunday morning, with clear skies expected later in the day.
