The science is about the physics and chemistry of the upper atmosphere; especially in regions of ionized gas: Aeronomy is the scientific study of the very high atmospheric regions of the Earth and other planets where the ionization of gas takes place.

Aeronomy is also concerned with the atmospheres around comets and satellites, or any other atmosphere where ionization, particularly of oxygen, takes place.

aero-odontodynia (s) (noun) (no pl)
Dental pain associated with the reduction in atmospheric pressure in high-altitude flying: Aero-odontodynia results from the difference in pressure that exacerbates existing pulpitis, particularly in connection with caries and restorations.

aeroparotitis (s) (noun) (no pl)
Swelling of one or both parotid glands due to the introduction of of air into the glands: Aeroparotitis may occur in those who play wind instruments, however it also occurs in excessive nose blowing.
