Infrared Spectroscopy of the Giant Planets

Most of our knowledge about the structure and composition of the giant planets’ atmospheres comes from infrared spectroscopy. As all solar system bodies, spectra of the giant planets exhibit two components, a reflected/scattered solar component which peaks at 0.5 mm, and a thermal emission which dominates at longer wavelengths, in the mid- to far-infrared range. In this review, I will summarize what we have learnt about (1) the atmospheric properties of the giant planets (thermal and cloud structure, composition), and (2) the elemental and isotopic ratios, which are diagnostics of their origin and evolution processes. Lessons will be drawn about what we can expect to learn from the infrared spectra of exoplanets.
