Cloud seeding has become an increasingly popular practice in the western United States, where states grapple with growing demands for water. Measuring how much precipitation cloud seeding produces has been a longstanding challenge. Researchers have developed a way to use radar and other tools to more accurately measure the volume of snow produced through cloud seeding.
