Delhi’s Air Quality ‘Moderate’, May Dip To ‘Poor’ On Sunday

The national capital's air quality was recorded in the 'moderate' category on Saturday morning, and is likely to turn poor on Sunday due to lowering temperatures and slow wind speed, a government forecasting agency said.

Delhi recorded an air quality index of 182 at 10:30 a.m., which falls in the moderate category. The24-hour average AQI was 180 on Friday.

An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

"The air quality is likely to deteriorate to the lower end of poor quality on Sunday," the System of Air Quality and Weather Forecasting and Research said.

It said an increase in farm fires was observed on Friday around Punjab, Haryana and neighbouring border regions and it is likely to impact Delhi in the coming days.

Also, there is a marked dip in minimum temperatures recorded in Delhi.

On Friday, it settled at 20.6 degrees celsius, which was two notches below normal and is likely to drop to 19 degrees celsius by Wednesday.

Low temperatures and stagnant winds help in accumulation of pollutants near the ground, affecting air quality.
