NEW DELHI: Light rain and beneficial wind velocity introduced air pollution ranges down considerably in Delhi and its suburbs on Monday, whereas climate specialists mentioned the air high quality is probably going to enhance additional. The metropolis’s air high quality index (AQI) improved to 300 at 9 am, which falls within the poor class, from 467 across the identical time on Sunday.

The neighbouring cities of Faridabad (256), Ghaziabad (292), Greater Noida (302), Gurugram (314) and Noida (312) recorded their AQI in “poor” and really poor” categories after braving “extreme” air quality on Saturday and Sunday.

Delhi had recorded the worst pollution levels on Diwali in the last four years due to the combined effect of stubble burning, firecrackers and unfavourable meteorological conditions.

The air quality on the day after Diwali was also the poorest since 2016.

The city recorded an overall AQI of 414 on Saturday (Diwali). On Sunday, the 24-hour average AQI stood at 435.

In a special report, the Central Pollution Control Board said that almost all pollutants reported higher values on Diwali day this year as compared to 2019. It could be attributed to bursting of firecrackers, higher share of stubble burning and unfavourable meteorology during the festival season, the CPCB said.

However, rain and high-velocity winds came to Delhi’s rescue this year.

Winds gusting up to 40 kilometre per hour swept away the pollutants, while light rainfall in the afternoon and evening on Sunday washed everything down.

Kuldeep Srivastava, the head of the India Meteorological Department, said the wind speed will be favourable for dispersion of pollutants on Monday as well.

The ministry of earth sciences’ air quality monitor, SAFAR, had also predicted that pollution levels may recede to the “poor” category “in case of sufficient rains and washout”.

The air quality is likely to stay in the “very poor” class on Tuesday and Wednesday, it mentioned.
