TL;DR: Early Cassini infrared observations of Titan show a stratopause at an altitude of 310 kilometers (and 186 kelvin at 15°S), and the concentrations of several stratospheric organic compounds are enhanced at mid- and high northern latitudes, and the strong zonal winds may inhibit mixing between these latitudes and the rest of Titan.

TL;DR: The Composite Infrared Spectrometer (CIRS) is a remote-sensing Fourier transform spectrometer on the Cassini orbiter that measures thermal radiation over two decades in wavenumber, with a spectral resolution that can be set from 0.5 to 15.5 cm− 1.

TL;DR: Diurnal surface temperature variations on Phoebe suggest a more porous regolith than on the jovian satellites, and Saturn's ring temperatures have radial variations down to the smallest scale resolved (100 kilometers).

TL;DR: Maps of temperatures and winds with high spatial resolution, obtained from spacecraft measurements of infrared spectra of Jupiter's stratosphere, find an intense, high-altitude equatorial jet with a speed of ∼140 m s-1, whose spatial structure resembles that of a quasi-quadrennial oscillation.
Jupiter's Atmospheric Temperatures: From Voyager IRIS to Cassini CIRS

TL;DR: Flamen et al. as discussed by the authors used data from the Voyager and Cassini Composite Infrared Spectrometer (CIS) data to generate global temperature maps of the planet in the troposphere and stratosphere, but to higher latitudes than were shown previously by Flasar et al., 2004a.
