The atmosphere of Saturn - An analysis of the Voyager radio occultation measurements

The Voyager 1 and 2 probes' radio links were used to study both the northern and southern latitudes of Saturn during occultation by that planet, yielding electron number density profiles for the ionosphere, and gas refractivity, number density, pressure, temperature, and ammonia abundance data for the troposphere and stratosphere. From the vertical pressure profiles obtained at different latitudes, it is possible to determine the size and shape of Saturn's isobaric surfaces.
