IIT-Kanpur Proceeds with Delhi Cloud-Seeding Despite IMD Warning
IIT-Kanpur conducted cloud-seeding trials in Delhi to combat air pollution, despite warnings from the India Meteorological Department that cloud conditions were unsuitable. The experiment failed to produce rain, but researchers say it provided valuable data. Experts remain skeptical about the effectiveness of cloud seeding in Delhi's winter climate.
IIT-Kanpur carried out cloud-seeding trials in Delhi on October 28, 2025, to address severe air pollution, even though the India Meteorological Department (IMD) had warned that cloud conditions were insufficient for artificial rain. The team used a mixture of silver iodide, rock salt, and common salt, but both attempts failed to produce rain. IIT-Kanpur's Director, Manindra Agrawal, acknowledged the IMD's negative feedback but stated the experiment was necessary to test the efficacy of their proprietary solution and gather baseline data. The institute believes that despite the current challenges, cloud seeding could be a potential emergency measure if conditions improve. However, experts from IMD and IITM Pune have consistently cautioned that Delhi's winter climate lacks the necessary moisture for effective cloud seeding. The scientific consensus is that cloud seeding is only suitable for enhancing monsoon rainfall and not for winter air pollution management. The Delhi government's push for cloud seeding reflects a history of seeking desperate measures to combat pollution, but the results remain uncertain and controversial. The experiment is part of a broader effort to explore innovative solutions, but the scientific community remains divided on its practicality and effectiveness in Delhi's unique climatic conditions.
