Why did Delhi's air quality reach the 'good' level?
On Tuesday morning at 5:30 am, Delhi's air quality index (AQI) fell to 29, placing it in the 'good' category. This improvement in the city's air was driven by persistent monsoon rain, which cleared pollutants from the air, combined with winds that prevented smog from settling. By 12:31 pm, the AQI had risen to a high of 57.
