The Composite Infrared Spectrometer (CIRS) is an instrument on the Cassini spacecraft, now orbiting Saturn. CIRS records infrared spectra of Saturn, its satellites, and its rings. The CIRS scientific team studies the temperature structure, dynamics, and composition of the atmosphere of Saturn and Titan. The team also studies the thermal structure of Saturn's rings, and the nature of warm structures on icy satellites such as Enceladus. CIRS is sensitive to wavelengths from 7 to 1000 micrometers, using several different detectors.

The full CIRS scientific team is international in scope, with co-Investigators located in the U.S., England, France, Germany, and Italy. Michael Flasar of Goddard's Planetary Systems Laboratory is the Principal Investigator. Others from the Planetary Systems Laboratory participating in the work are civil servants Carrie Anderson, Gordon Bjoraker, John Brasunas, Donald Jennings, and Paul Romani. Contractors and other local participants include Richard Achterberg, Valeria Cottini, Nicolas Gorius, Ever Guandique, Brigette Hesman, Monte Kaelberer, Andre Mamoutkine, Conor Nixon, and James Tingley.
