During a three-hour test over Alaska, Rainmaker’s drones released small amounts of silver iodide into cold clouds. The company says this helped form ice crystals that fell as rain or snow, producing an estimated 71 million liters of additional precipitation.

Rainmaker uses weather algorithms, radar, and satellite data to select clouds and time each seeding flight. Atmo’s AI models help identify clouds with high seeding potential. The estimate is based on Rainmaker’s own analysis.
