| Summary:
Atmospheric compositions for rocky exoplanets will depend strongly on the
bulk planetary composition and the orbital position of the planet.
Non-traditional gases may be present in the atmospheres of exceptionally hot
planets. Atmospheres of more clement planets will depend on the abundances of
volatiles acquired during planet formation and atmospheric removal processes,
including escape, condensation, and reaction with the surface. While the
observations of exoplanet atmospheres to date has focused on giant planets, a
series of new space and ground-based observatories over the coming decade will
revolutionize the precision and spectral resolution with which we are able to
probe exoplanet atmospheres. This article consolidates lessons learned from the
study of giant planet atmospheres, and points to the observations and
challenges on the horizon for terrestrial planets.
