Aeronomy is the science of the upper region of the atmosphere, where dissociation and ionization are important. The term aeronomy was introduced by Sydney Chapman in 1960.<ref>Andrew F. Nagy, p. 1-2 in ''Comparative Aeronomy'', ed. by Andrew F. Nagy ''et al.'' (Springer 2008, {{ISBN|978-0-387-87824-9}})</ref> Today, the term also includes the science of the corresponding regions of the atmospheres of other planets.  Research in aeronomy requires access to balloons, satellites, and [[sounding rockets]] which provide valuable data about this region of the atmosphere.  [[Atmospheric tide]]s play an important role in interacting with both the lower and upper atmosphere.  Amongst the phenomena studied are [[upper-atmospheric lightning]] discharges, such as luminous events called red [[sprites (lightning)|sprites]], sprite halos, blue jets, and elves.
