The Ammonia Infrared Absorption Reinvestigated in Connection with the Voyager Mission to Jupiter and Saturn

Abstract

The scientific objectives of the IRIS experiment of the Voyager 1 and 2 missions[1] (encounters with Jupiter in March and July 1979) are the study of the atmospheres of Jupiter, Saturn and possibly Uranus, from radiometric measurements in the infrared by means of a Michelson interferometer. For the first time, more than 50000 spectra of Jupiter were recorded with a spectral resolution of 4.3 cm-1.
