    Delhi Cloud Seeding: Rs 25 Crore Winter Solution Could Reduce Air Pollution by 10%

    Oct 29, 2025 07:17 pm CST

    IIT Kanpur's cloud seeding operations in Delhi show potential to reduce PM2.5 and PM10 pollutants by 6-10%. While yesterday's attempts didn't produce rain due to low moisture content, Director Manindra Agrawal explains that implementing this technology throughout winter would cost approximately Rs 25 crore - a fraction of Delhi's pollution control budget. Though not a permanent solution, cloud seeding offers a strategic intervention until long-term pollution control measures take effect.

    Delhi's Third Cloud Seeding Trial Since 1957: Fighting Air Pollution With Artificial Rain Technology

    Oct 29, 2025 02:10 am CST

    After a 53-year gap, Delhi has resumed cloud seeding experiments to combat severe air pollution. The recent collaboration between the Delhi government and IIT-Kanpur marks the city's third such trial since 1957, using advanced technology to induce artificial rainfall. The Rs 3.21 crore project employs specialized aircraft releasing seeding materials into clouds, potentially offering a solution to Delhi's winter pollution crisis. Previous experiments showed promising results, with similar technology increasing rainfall by up to 46% in other Indian regions.

    Delhi has conducted two cloud seeding trials to stimulate rainfall and reduce severe air pollution, as the city's AQI continues to exceed 300 in multiple areas. Despite a 77.5% reduction in farm fires, PM2.5 levels have reached 488 micrograms per cubic meter after Diwali—nearly 100 times WHO recommendations. The government has partnered with IIT Kanpur for five trials costing Rs 3.21 crore, though low cloud moisture content may limit effectiveness.

    Delhi's First Cloud Seeding Trial: Combating Air Pollution Through Artificial Rainfall Technology

    Oct 28, 2025 02:53 am CST

    Delhi government prepares for its first cloud seeding trial to combat winter air pollution, pending favorable weather conditions. The IIT Kanpur-led project, costing Rs 3.21 crore, aims to induce artificial rainfall through silver iodide and sodium chloride compounds, with multiple government agencies providing necessary clearances for implementation.

    Inside Delhi's Cloud Seeding Initiative: How Artificial Rain Could Combat Severe Air Pollution

    Oct 24, 2025 06:27 pm CST

    Delhi prepares for its first artificial rainfall on October 29 to combat dangerous post-Diwali air pollution. Following a successful trial using silver iodide and sodium chloride, this weather modification technique builds on previous research conducted in 2018 by the Ministry of Earth Sciences. Despite delays due to unfavorable conditions, the Rs 3.21 crore project aims to provide much-needed relief from Delhi's deteriorating air quality.
