In the Delhi University area, the AQI was recorded at 399, also in the ‘very poor’ category. In the Mathura Road area, it was 380. In Gurugram, it was 349 while in Noida the AQI was recorded at 411.
Today morning the air quality in the national capital remained in the ‘very poor’ category with the overall AQI at 309.
“Local surface winds are 6 to 8 km/h (Max Temperature 32 deg C; Min 14-15 deg C) for the next three days that cause weak dispersion of pollutants. Peak ‘Mixing layer height’ during daytime (~1.0-1.5 km) leads to moderate vertical dispersion of pollutants,” read SAFAR’s official statistics.
The air quality watchdog also informed that strong winds at the transport level blowing from the northwest direction from stubble burning areas are likely to transport pollutants to Delhi and its share in Delhi’s PM2.5 is likely to increase further.
According to the SAFAR forecast, the air quality of the city will continue under the “very poor category” on Sunday.
