      Some mining towns had problems where their smelter fumes when mixed with the rain created an acidic rain that stripped paint off of cars. There was daily wind monitoring used to help settle the insurance claims.

          Raindrops are at least. Water vapor need consensation nuclei to form around to create a raindrop.

          That’s what cloud seeding is based on. They introduce particulates for the drops to form around and fall.
