In a decisive move to combat hazardous air pollution, the Delhi government has committed to funding the entire cost of artificial rain. Officials reveal that if the central government supports this initiative, the first phase of artificial rain could be implemented in the city by November 20.
A senior government official shared, "In a significant development, the Delhi government has decided to bear the cost of artificial rain that could be made to happen by November 20 if the Centre extends its support."
The decision comes after discussions with a team from IIT-Kanpur, which suggested inducing artificial rain through cloud seeding technology. According to the team, successful trials in Kanpur demonstrated a 6 out of 7 success rate. The technology's feasibility during winter to reduce air pollution levels in Delhi was confirmed.
For this big project to happen, the Delhi government has to get approvals from 10 central government ministries, agencies, and also the Uttar Pradesh government. They expect it to cost about ₹1 lakh for every square kilometer.
The IIT-Kanpur team recommends initiating a pilot cloud seeding covering 300 square kilometres in the first phase, given the air pollution emergency in Delhi. The artificial cloud seeding's success depends on factors like clouds with a minimum of 40% moisture content, appropriate aircraft and setup, seeding materials, and necessary permissions.
Based on meteorological predictions, sufficient clouds over Delhi are expected around November 20-21, aligning with the experts' advice to conduct the first phase of cloud seeding during those days. Chief Secretary Naresh Kumar has been tasked with coordinating with the IIT-Kanpur team and central ministries, submitting the proposal for artificial rain to the Supreme Court through an affidavit.
Artificial rain through cloud seeding involves dispersing substances like silver iodide, potassium iodide, or dry ice into the air, encouraging condensation and precipitation. This weather modification technique, used globally, holds promise for alleviating Delhi's air pollution crisis, showcasing the Delhi government's commitment to exploring innovative solutions.
