New Delhi: The Central Pollution Control Board (CPCB) is mulling inducing artificial rain in Delhi after Diwali to wash away hazardous pollutants that is plaguing the national capital. A senior CPCB official said they are in talks with the Indian Institute of Technology Kanpur and the India Meteorological Department (IMD) for inducing artificial rain after Diwali when the pollution is expected to reach “severe-plus emergency” stage.
The official said they are waiting for meteorological conditions to become stable and then use cloud seeding for inducing artificial rain. Cloud seeding is the process of combining different kinds of chemical agents — including silver iodide, dry ice and even common table salt — with existing clouds in an effort to thicken the clouds and increase the chance of rain or snowfall.
An IIT Kanpur professor said weather conditions are being monitored to become favourable for creating artificial rain.
We are supporting the project by providing salt mix for inducing artificial rain. The weatherman is monitoring weather conditions to become favourable for creating artificial rain, the IIT Kanpur professor, who is part of the project, said.
In 2016, the government tried to explore the possibility of cloud seeding for artificial rain but the plan never worked out. Last year, the government has proposed the possibility of reducing dust by watering Delhi from a helicopter to Union Minister Harsh Vardhan.

Delhi’s air quality has deteriorated to alarming levels in the past three weeks. Delhi’s air quality was recorded in ‘very poor’ category on Tuesday as wind continued to blow from regions where there is rampant stubble burning, authorities said, warning of severe spike in pollution levels after Diwali even if “partial toxic crackers” are burnt compared to last year.
The overall Air Quality Index (AQI) was recorded at 394, which falls in the ‘very poor’ category, according to data by the Central Pollution Control Board.
NDTV – Dettol Banega Swachh India campaign lends support to the Government of India’s Swachh Bharat Mission (SBM). Helmed by Campaign Ambassador Amitabh Bachchan, the campaign aims to spread awareness about hygiene and sanitation, the importance of building toilets and making India open defecation free (ODF) by October 2019, a target set by Prime Minister Narendra Modi, when he launched Swachh Bharat Abhiyan in 2014. Over the years, the campaign has widened its scope to cover issues like air pollution, waste management, plastic ban, manual scavenging and menstrual hygiene. The campaign has also focused extensively on marine pollution, clean Ganga Project and rejuvenation of Yamuna, two of India’s major river bodies.
