Aeronomy is the study of the Earth's upper atmosphere, particularly the regions where the atmosphere begins to interact with outer space. This field encompasses research into the physical and chemical processes that influence the behavior and composition of the atmosphere at high altitudes, typically above 30 to 50 kilometers (19 to 31 miles), where phenomena like the ionosphere and various layers of the atmosphere, including the thermosphere and exosphere, are located.
