Overview
- The Delhi regional government and IIT Kanpur conducted the Oct. 28 aircraft-based experiment to reduce smog.
- Researchers dispersed silver iodide into clouds to encourage raindrop formation intended to wash out pollution.
- No noticeable rainfall was observed during the test, and local readings showed pollution remained elevated.
- Officials say further attempts are planned for now and a longer-term program could follow only if trials succeed.
- Reports put the cost at about ¥10 million per attempt, and experts note the method works only when clouds hold sufficient moisture; New Delhi’s pollution typically worsens from autumn into winter.
