The homosphere is the region of the atmosphere where gases are so evenly mixed that they behave as if they were a single gas. It extends from the surface of the Earth up to about 80-100 km above sea level, and is primarily composed of nitrogen and oxygen gases. This region is characterized by a fairly constant composition and temperature.
