Venus: A planetary window into early Earth

open access: yes地球与行星物理论评, 2022
Venus is the most similar planet to the Earth in the solar system in terms of planet size, mass and orbital velocity. Since the early 1960s, Venus has been an important target for human deep space exploration.

Brief communication: Lower-bound estimates for residence time of energy in the atmospheres of Venus, Mars and Titan [PDF]

open access: yesNonlinear Processes in Geophysics, 2021
The residence time of energy in a planetary atmosphere, τ, which was recently introduced and computed for the Earth's atmosphere (Osácar et al., 2020), is here extended to the atmospheres of Venus, Mars and Titan.

High-Temperature Oxidation of Magnesium- and Iron-Rich Olivine under a CO2 Atmosphere: Implications for Venus

open access: yesRemote Sensing, 2023
Understanding crust–atmosphere interactions on Venus is fundamentally important to interpretations of Venus’ surface spectroscopic data. Olivine, in basaltic crust, is oxidized under a heated CO2 atmosphere.

The Influence of Cloud Condensation Nucleus Coagulation on the Venus Cloud Structure

open access: yesThe Planetary Science Journal, 2023
We present the Venus version of PlanetCARMA and demonstrate the significance of coagulation properties on the structure of the Venus cloud system. The composition of the smallest mode of particles in the Venus atmosphere, which likely serve as cloud ...

A WISPR of the Venus Surface: Analysis of the Venus Nightside Thermal Emission at Optical Wavelengths

open access: yesThe Planetary Science Journal, 2023
Parker Solar Probe (PSP) conducted several flybys of Venus while using Venus’ gravity for orbital adjustments to enable its daring passes of the Sun. During these flybys, PSP turned to image the nightside of Venus using the Wide-field Imager for Solar ...

The June 2012 transit of Venus. Framework for interpretation of observations [PDF]

open access: yes, 2012
Ground based observers have on 5/6th June 2012 the last opportunity of the century to watch the passage of Venus across the solar disk from Earth. Venus transits have traditionally provided unique insight into the Venus atmosphere through the refraction ...

Pioneer Venus atmospheric observations

open access: yesPhilosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1981
Some selected results from the scientific experiments on the recent Pioneer missions to Venus are reviewed, with particular emphasis on data from the infrared remote sensing experiment on the orbiter. Various aspects of the structure, dynamics and energy budget of the atmosphere, as revealed by the measurements, are presented for discussion.

The Effect of Recent Venus Transit on Earth’s Atmosphere

open access: yesAnnals of Geophysics, 2006
Some experiments on June 8, 2004, the day of transit of Venus across the Sun, were undertaken at Kolkata (latitude: 23034? N) to observe effect, if any, of transit of Venus on FWF, ELF and VLF amplitudes.
