what chemical is used for cloud seeding?
310830
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.

United Arab Emirates In the UAE, cloud seeding is being conducted by the weather authorities to create artificial rain. The project, which began in July 2010 and cost US$11 million, has been successful in creating rain storms in the Dubai and Abu Dhabi deserts.

As it is the highest form of cloud I'd suggest that the noctilucent clouds are the very least likely ones to produce precipitation that reaches the ground. These clouds are found way up around 80 kilometres above the surface of the earth.

There must be three main ingredients present in order for clouds to form: Moisture - There must be sufficient water vapor in the air to build a cloud. Cooling air - The air temperature must decrease enough for water vapor to condense.

The active material may be a powder such as potassium bicarbonate (KHCO3), liquid water, an evaporating fluorocarbon or the propelling agent itself. The most effective and common fluorocarbon used until recently for this application had been bromochlorodifluoromethane (CF2ClBr), referred to as halon 1211.

A common example of deposition is 'rain out': compounds that are soluble in water can be removed from the atmosphere by precipitation. This phenomenon is responsible for acid rain. The most abundant CFCs emitted into the troposphere are CFC 11 and CFC 12.

The United Arab Emirates is one of the first countries in the Persian Gulf region to use cloud seeding technology. It adopted the latest technologies available on a global level, using sophisticated weather radar to monitor the atmosphere of the country around the clock.

MAKING CLOUDS AND RAIN First, we need two basic ingredients: water and dust. On Planet Earth, naturally occurring clouds are composed primarily of water in its liquid or solid state.
