Lithometeors are meteors that are observed in the atmosphere on the earth's surface or in the sky in the field of meteorology. The name is derived from “litho”, ancient Greek [] for “stone” (note: including in the sense of sand and dust), and “meteor”, from ancient Greek [metéōros], “floating in the air”. Unlike electrometeors, hydrometeors and photometeors, they are associated with suspended particles that are not made of water. Solid and liquid components of the atmosphere in whose composition water plays no or at least almost no role are also referred to as aerosols.
