Delhi Rain: Reprieve from pollution for residents as noxious haze dissipates after overnight rainfall; weather will be like this in North & South India on Diwali

New Delhi: While Delhi Government is  considering artificial rainfall to control pollution, people got relief after the overnight rainfall in Delhi. The rain that started in Delhi on Thursday night continued till Friday (November 10) morning. 

Overnight showers in New Delhi and its surrounding areas provided a welcome reprieve for residents as the noxious haze dissipated, leading to a marginal improvement in air quality. The meteorological agency anticipates a further alleviation of pollution ahead of Diwali on Sunday. This development coincides with ongoing discussions between the Delhi government and the Indian Institute of Technology (IIT) Kanpur about implementing artificial rain measures across the national capital to address the escalating air quality concerns.

New Delhi grapples with the aftermath of a week characterized by severe pollution, with concentrations of harmful particles reaching levels up to 100 times higher than those recommended by the World Health Organization, making it the world's most polluted city until Thursday.

Significant reduction in levels of pollutants

As of 7 am today on Friday, the overall air quality in Delhi measured 407, according to data from the government's air-quality monitoring agency SAFAR. Particularly affected areas include Ashok Vihar (443), Anand Vihar (436), Bawana (433), Rohini (429), and Punjabi Bagh (422). The air quality situation is similarly grim in neighboring cities, with Noida recording an average AQI of 475, Faridabad 459, Gurugram 386, and Ghaziabad 325.

Data indicates a significant reduction in the levels of pollutants PM 2.5 and PM10 after 4 am across the national capital and its environs.

Meanwhile, the Delhi government is actively implementing anti-pollution measures and is exploring the possibility of artificial rain to address the pollution crisis. On Thursday night, several ministers of the Aam Admi Party were observed on the ground inspecting the execution of these anti-pollution initiatives.

The Supreme Court is set to review existing measures aimed at improving air quality, considering further restrictions on road traffic, and addressing the contribution of dust from construction—an integral factor in the city's pollution problems.

Gufran Beig, the founder director of the Central government's air-quality monitoring agency SAFAR, emphasized the need for substantial and widespread rainfall to cleanse the pollutants, cautioning that light rains could exacerbate the situation.
