What is Cloud Seeding?

Cloud seeding is a form of weather modification that increases the efficiency of a cloud by enhancing its natural ability to produce precipitation.


Why do we seed clouds?

In Idaho, cloud seeding is used during the cold season to augment high elevation snowpack, our primary storage reservoirs. In other areas of the United States and around the world, cloud seeding is also used for rain enhancement during warm seasons, hail mitigation to reduce damage to crops and infrastructure, and for fog suppression around airports.
