Icarus, 1972
Photographs of Venus taken in ultraviolet light from Sept. 29, 1963, to May 29, 1971, indicate a general planet-wide circulation in the upper atmosphere of that planet having velocities which varied with time from -87 to -127m/sec at the equator. Positional measurements on 67 pairs of photographs which show the recurrence of similar patterns after ...

In the context of an International Space Science Institute(ISSI) working group, we have conducted a project to compare the most recent General Circulation Models (GCMs) of the Venus atmospheric circulation. A common configuration has been decided, with simple physical parametrization for the solar forcing and the boundary layer scheme.

Venus Lower Atmospheric Composition: Preliminary Results from Pioneer Venus
Science, 1979Initial examination of data from the neutral mass spectrometer on the Pioneer Venus sounder probe indicates that the abundances of argon-36, argon-38, and neon-20 in the Venus atmosphere are much higher than those of the corresponding gases in Earth's atmosphere, although the abundance of radiogenic argon-40 is apparently similar for both planets.

Venus: Lower Atmosphere Not Measured
Science, 1968The common ranges of pressure and temperature of the atmosphere of Venus measured last October establish the connection between the Soviet Venera 4 altitude scale and the United States Mariner V radial scale. But if the Venera 4 measurements extended to the surface, as claimed, this comparison implies a radius of the planet which is about 25 kilometers

Venus: An Isothermal Lower Atmosphere?
Science, 1969Use of Earth-based microwave data in extrapolating the atmospheric profile of Venus below the region probed by Mariner V and Venera 4 reveals an isothermal layer at 670° ± 20°K that extends to an altitude of 7 ± 2 kilometers. This model gives a value of 6054.8 kilometers for the radius of Venus, and agreement with brightness spectrum, radar cross ...

Venus upper atmosphere structure
Journal of Geophysical Research: Space Physics, 1980From analysis of the orbiter atmospheric drag (OAD) data obtained from the orbital decay of the Pioneer Venus orbiter from December 9, 1978, to August 7, 1979, atmospheric densities have been determined and tabulated near 16°N latitude between 140 and 190 km for all times of day.

This chapter discusses the greenhouse effect and climate evolution using Venus as an example. Venus mostly has an Earth-like inventory of volatile gases—the basic ingredients of atmospheres and oceans—but with one glaring exception: water. Earth's ocean is 300 times as massive as its atmosphere.
