Planetary Probe: Origin of Atmosphere of Venus

Science, 1969
The high temperatures and chemical composition, as determined by space probe and terrestrial observation, suggest that the present atmosphere of Venus has formed by chemical interaction with the lithosphere. Although the precise reactions have not been identified, good theoretical approximations to the molecular abundance may be obtained from reactions

Replicating the discovery of Venus’s atmosphere

Physics Today, 2013
The 2012 transit of Venus gave us a chance to reproduce Mikhail Lomonosov’s 1761 observation and demonstrate the excellent quality of 18th-century telescopes.

The evolution of venus' atmosphere

Planetary and Space Science, 1969
Abstract Although the atmospheres of the terrestrial planets may have originated by similar mechanisms and during a similar epoch, their subsequent developments followed divergent paths, partly as the result of different Sun-planet distances. On such a premise a self-consistent model has been devised to explain the present dense CO2 atmosphere of ...

The upper atmosphere of Venus

Journal of Geophysical Research, 1968
The photochemistry of CO2 on Venus is discussed in the light of recent data obtained from Mariner 5 and Venus 4. It is suggested that preliminary data indicate that recombination of CO and O proceeds rapidly by formation of an unstable CO3 complex. Models for the thermal structure of the Venus atmosphere are presented. These models are characterized by

Evolution of the Atmosphere of Venus

Journal of the Atmospheric Sciences, 1975
Abstract The runaway greenhouse effect provides the most plausible explanation for the divergent evolution of the atmospheres of Venus and Earth. It has not yet been convincingly demonstrated that the atmosphere of Venus is in chemical equilibrium with the surface.

Dust in the Lower Atmosphere of Venus

Science, 1969
Terminal velocities of dust particles have been calculated for two model atmospheres of Venus; data are derived from measurements of Mariner V and Venera 4. The vertical wind velocities required to maintain dust aloft in the lower atmosphere of Venus are less than one-half the magnitude of those needed on Earth.

The aeolosphere and atmosphere of Venus

Journal of Geophysical Research, 1961
A self-consistent model of the Venus atmosphere that satisfies the multitude of existing observational data is proposed. Its main properties and the line of reasoning are described as follows. The radiative greenhouse effect cannot account for a surface temperature of 570°K.

Radiation in the atmosphere of Venus

2007
This chapter reviews the observations of the radiative fluxes inside and outside the Venusian atmosphere, along with the available data about the planetary energy balance and the distribution of sources and sinks of radiative energy. We also briefly address the role of the heat budget on the atmospheric temperature structure, global circulation ...
