Air quality drops in Delhi ahead of winter every year, when cold air traps pollutants from various sources, including vehicles, industries, construction dust and burning of agricultural waste. Scientists expect cloud cover over the city around November 20 and hope it will be large enough and with high enough moisture content to cause heavy rain through salt-seeding, said Manindra Agrawal, a scientist at the Indian Institute of Technology. in Kanpur, who conducts the trial.

The project, estimated to cost 10 million rupees ($120,000) per 100 square kilometers (38.6 square miles), will involve cloud-spraying a mixture of salts that include silver iodine, Agraëal said.

"We don't expect such a big cloud covering the whole of Delhi, but a few hundred kilometers would be good," he told Reuters.

The local government of the city of 20 million people, spread over about 1,500 square kilometers (579 square miles), has already closed all schools, banned construction activities and said it would impose restrictions on the use of vehicles to control pollution.
