“…Wildt (1937) first reported the detection of Jovian ammonia observed as absorption in the spectrum of sunlight reflected from the visible clouds. The first relevant radio observations of Jupiter were those of Alsop and Giordmaine (1961) at 3 cm, Welch (1963) at 8.35 mm, andKalaghan andWulfsberg (1968) at 8.6 mm. All of these were single antenna measurements in which the planet was not spatially resolved.…”

The availability of new accurate radio flux densities of Jupiter in and around the λ1.3 cm ammonia absorption band, one from groundbased radio data and five from the WMAP satellite, permits reexamination of the structure of the Jovian upper troposphere. These flux densities, with accuracies of 1-3%, indicate that the Jovian atmospheric ammonia is globally subsaturated within and above the ammonia cloud tops, 0.4 bar ≤ P ≤ 0.6 bar, and subsolar (by a factor of 2) below the cloud base, 0.6 bar ≤ P ≤ 2 bar.

A survey of current knowledge about Jupiter, Saturn, Uranus, Neptune, Pluto, and their satellites is presented. The best available numerical values are given for physical parameters, including orbital and body properties, atmospheric composition and structure, and photometric parameters. The more acceptable current theories of these bodies are outlined with thorough referencing offering access to the details. The survey attempts to cover the literature through May 1, 1972.
