Rainmaking (1968) - A Film On Cloud Seeding - CSIRO Documentary

The Australian Government has been using silver iodide for weather modification since the 1950s.

The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research.

"Making clouds rain has been the subject of intensive research in several countries since the mid-40s. This study is the story of rainmaking in Australia – from the first tentative experiments with dry ice to the present, large-scale operations using silver iodide as the seeding agent. The film gives an account of the basic theory of cloud-seeding and outlines the techniques used in its practical application."
