The materials used in cloud seeding include two primary categories, tied to the type of precipitation process involved. One category includes those which act as glaciogenic (ice-forming) agents, such as silver iodide, dry ice and compressed liquid propane or carbon dioxide, which are appropriate in cloud systems where the precipitation process is primarily cold (colder than freezing). Of the ice-forming materials, the most commonly used is silver iodide. 3, record 1, English, - ice%2Dforming%20substance

Il s'agit le plus souvent de fines particules d'iodure d'argent ou parfois de neige carbonique. Divers procédés peuvent être mis en œuvre pour assurer un tel ensemencement : brûleurs au sol de solutions d'iodure d'argent dont les fumées sont censées pénétrer dans le nuage grâce aux courants ascendants naturels, fusées libérant le produit glaçogène sur une partie de sa trajectoire, obus explosant à un niveau approprié de nuage, ensemencement par avion. 1, record 1, French, - produit%20gla%C3%A7og%C3%A8ne
