## How we Seed the Clouds. Cloud Seeding is a scientifically validated method of weather modification, involving the controlled dispersion of seeding materials into clouds. These techniques offer versatility, allowing for the augmentation of precipitation (rain or snowfall) within targeted areas, as well as hail suppression and fog dispersion. Our product range caters to diverse scenarios, enabling application within both warm and cold cloud environments. Cloud seeding in cold clouds. Cloud seeding in warm clouds. ### Cloud Seeding Application. ### Cloud-Top Seeding by Aircraft. This extremely effective all-weather method uses light aircraft to transport BIP and ejectable flares, and aerosol generators above into the cloud to release seeding materials along the flight path. ### Areal Cloud-Base Seeding. This widely successful method uses Cloud Seeding Aircraft or Smart Cloud Seeding Drones to deliver seeding materials to the updrafts that feed the clouds where the particles are naturally dispersed. ### Ground-based Cloud Seeding.

Written and fact-checked by. **fog dispersal**, artificial dissipation of fogs, usually by seeding or heating. Many attempts have been made to clear fogs at temperatures above freezing (0 °C [32 °F]) by seeding them with salt particles, by downwash mixing (that is, using whirling helicopter rotors to pump dry air downward into the fog layer), and by heating the air near landing strips with burners; however, these techniques have been shown to provide only short-term relief under limited conditions. Fog dispersal at temperatures below freezing, however, is regularly performed at many airports by seeding them with solid and liquid carbon dioxide or with propane gas sprayed from the ground.

## What is Cloud Seeding? Illustration on how cloud seeding works with silver iodide rising into the clouds and resulting in ice crystals that grow large enough to fall as snow. ## How we Cloud Seed. Most cloud seeding operations, including those run by DRI, use a compound called silver iodide (AgI) to aid in the formation of ice crystals. When storm systems move through one of our cloud seeding project areas, a solution containing a small amount of silver iodide is burned from ground-based generators or released from aircraft. Cloud seeding is used all over the world as a method for enhancing winter snowfall and increasing mountain snowpack, supplementing the natural water supply available to communities of the surrounding area. At a study site in the Snowy Mountains of New South Wales, Australia, a five-year cloud seeding project designed by DRI resulted in a 14 percent increase in snowfall across the project area.

## Planned Weather Modification through Cloud Seeding. One tool available for mitigating some of these weather impacts is planned weather modification through cloud seeding. Planned weather modification programs benefit from a comprehensive understanding of the physical processes responsible for desired modification effects. Recent improvements in the composition and techniques for dispersion of seeding agents, observational technology, numerical cloud models, and in physical understanding of cloud processes permit ever more detailed design and targeting of planned weather modification effects, and more accurate specification of the range of anticipated responses. Rigorous attention to evaluation of both operational and research programs is needed to help develop more effective procedures and to improve understanding of the effects of cloud seeding. Weather modification techniques other than cloud seeding have been used in various areas of the world for short periods of time to achieve goals similar to those of cloud seeding. 1) Efforts should continue to improve understanding of the targeted cloud and precipitation processes in planned modification.

Cloud seeding is a physical process/Fundamentals/Chemical_Change_vs._Physical_Change) whereby a seeding agent comprised of minute particles is released into an **EXISTING** cloud formation with Supercooled Liquid Water (SLW). A seeding agent, most commonly Silver Iodide (AgI), is then released into the existing storm cloud by an aircraft and/or by ground-based generators. The Seeded and Natural Orographic Wintertime clouds: the Idaho Experiment (SNOWIE) utilized a full outfitted weather research aircraft to fly directly into clouds and release silver iodide plumes to detect and measure the impacts of seeding. An aircraft flies either through or above an ACTIVE storm cloud releasing a seeding agent (Silver Iodide) into the cloud that has favorable conditions for ice crystal formulation. Cloud seeding is the process of inputting a solid particle (nucleus) into an EXISTING cloud formation, that liquid water can formulate ice around, and essentially deplete the cloud by turning its water content into ice.

# A Study on the Effectiveness of SCD Seeding Fog Dissipation Mechanism Using LiDAR Sensor. The experimental equipment for this study is as follows: It consists of a scale for measuring the amount of water that escapes through the humidifier, a seeding machine for SCD seeding, and a camera and LiDAR sensor for monitoring fog generation to dissipation. * Using LiDAR sensor measurement results and camera images, the tendency of the fog dissipation method with natural and SCD seeding dissipation was analyzed. As a consequence, the effect of SCD seeding on improving visibility when compared to natural dissipation under cold fog conditions was proven based on LiDAR sensor distance data and camera images.
