After Diwali celebrations, Delhi’s air quality was initially recorded as ‘very poor’, but improved to ‘poor’ the following day due to strong surface winds dispersing pollutants. Despite a ban on firecrackers being violated, air quality improved with an AQI of 291 on Saturday morning compared to 339 on Friday evening. However, real-time data showed PM2.5 levels exceeding safe limits, highlighting the impact of firecrackers. Experts attribute the improvement to the winds and expect them to continue until Sunday. The AQI ranges from ‘good’ to ‘severe’, with ‘poor’ and ‘very poor’ categories indicating levels from 201 to 400.
