Cloud Seeding Trials in Delhi: A Step Towards Pollution Control despite Minimal Rainfall

Amidst growing concerns over pollution, recent cloud seeding trials in Delhi, led by the local government alongside IIT-Kanpur, brought minimal rain but valuable insights. According to IIT-Kanpur Director Manindra Agrawal, the trials were economically efficient, especially when compared to exorbitant pollution control costs.

The trials, conducted over an expanse covering 300 square kilometres, yielded important data despite the low success rate in inducing rain. While the trials recorded meager rainfall in Noida and Greater Noida, Agrawal reaffirmed that its broader objective to gather data was met successfully.

Agrawal elaborated on the scientific process, emphasizing the trials' potential to reduce air pollution concentrations, albeit modestly. Utilizing a blend of common salt, rock salt, and silver iodide, the attempt aimed to condense moisture into rain droplets. Another scheduled trial was postponed due to insufficient moisture levels.
