Title:  The Atmospheres of Extrasolar Giant Planets
 
Abstract:  The bulk of exoplanet science to date has focused on planet detection with large-scale ground-based surveys 
and space-based facilities such as the Kepler Space Telescope. The past decade, however, has seen steady growth in 
observational and theoretical efforts aimed at understanding global chemical, radiative, and dynamical processes shaping 
exoplanet atmospheres.  There now exists a substantial amount ground and space-based observations that aim to probe 
atmospheric composition and thermal structure of these distant worlds. This new wealth of observational data has 
required refinement of methodologies and atmospheric theory, many with roots in solar system studies, used to interpret 
these data. Additionally, novel observational techniques and specialized general circulation models have allowed probes 
of the three-dimensional nature of exoplanet atmospheres, despite the limitations of spatially unresolved observations. 
Here I will review our current understanding of extrasolar giant planet atmospheres, dominated by the hot Jupiter 
population, which are in very different chemical, radiative, and dynamical regime compared with solar system giant 
planets. The next twenty years will bring continued growth in both exoplanet theory and observations that will further 
bridge the gap between our understanding of extrasolar and solar systems giant planets.
