What was the objective of the test flight conducted by Indian Institute of Technology Kanpur regarding cloud seeding?

Indian Institute of Technology Kanpur has successfully conducted a test flight for cloud seeding.  Cloud seeding involves the utilisation of various chemical agents such as silver iodide, dry ice, common salt, and other elements with the aim of enhancing the probability of rains. The project was initiated a few years ago and is headed by the Computer Science and Engineering Department of IIT Kanpur. The flight went up to an approximate height of 5,000 feet. It landed on the IIT Kanpur lab airstrip after successfully completing the test ride. The experiment was conducted with due approval from the Directorate General of Civil Aviation (DGCA). A Cessna aircraft was flown from the flight laboratory of IIT Kanpur with cloud seeding attachments procured from a manufacturer in the US.
