SUMMARY:Airglow in the atmospheres of the terrestrial planets
DESCRIPTION:Airglow in the atmospheres of the terrestrial planets\nDr. Anto
 nio García Muñoz\n\nThere is a multitude of photochemical processes occu
 rring in a planet's atmosphere. Some of these processes occur with an exce
 ss of energy and lead to products in the form of excited atoms, molecules 
 and ions.In specific cases, these gases radiate at wavelengths that range 
 from the UV to the NIR. Solar light is the ultimate cause of these airglow
  emissions, but traditionally one distinguishes between the day airglow (d
 ayglow), and the night airglow (nightglow). The contribution of the Sun to
  the excitation of the emitting gas is more immediate in the day glow than
  in the nightglow. The airglow makes it possible to remotely investigate t
 he chemical kinetics, energetic balance and dynamics of a planetary atmosp
 here. In the talk, I will go over some of the air glow missions that are k
 nown to exist in the atmospheres of the Earth, Mars and Venus. The example
 s illustrate some of my recent work, and include theoretical modelling and
  the interpretation of observational data. There is a long record of contr
 ibutions to the nightglow from observations carried out at ground-based te
 lescopes. I will briefly comment some of these.\n
