The Atmospheric Dynamics of Venus [PDF]

open access: yesSpace Science Reviews, 2017
We review our current knowledge of the atmospheric dynamics of Venus prior to the Akatsuki mission, in the altitude range from the surface to approximately the cloud tops located at about 100 km altitude. The three-dimensional structure of the wind field in this region has been determined with a variety of techniques over a broad range of spatial and ...

The second Venus flyby of BepiColombo mission reveals stable atmosphere over decades [PDF]

open access: yesNature Communications, 2023
Studies of the Venusian mesosphere provide important information about the current state of the entire Venusian atmosphere. This includes information about the dense cloud structure, its vertical thermal profile, temperature fields, and the resulting ...

Life on Venus? [PDF]

open access: yesLife
Venus is not generally at the forefront when considering extraterrestrial life. Yet, based on the physical similarities and proximity to Earth and with the little knowledge of its evolutionary history, there is a possibility that Venus may have hosted ...

Comparison of the greenhouse effect between Earth and Venus using multiple atmospheric layer models [PDF]

open access: yesE3S Web of Conferences, 2020
To better understand the mechanisms of global warming, we developed a one atmospheric layer model for Earth and a multiple atmospheric layer model (N = 111) for Venus.

Ammonia and Phosphine in the Clouds of Venus as Potentially Biological Anomalies

open access: yesAerospace, 2022
We are of the opinion that several anomalies in the atmosphere of Venus provide evidence of yet-unknown processes and systems that are out of equilibrium.

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.

Generation of gravity waves from thermal tides in the Venus atmosphere

open access: yesNature Communications, 2021
Gravity waves are observed in Venus atmosphere, but their characteristics are not well-known. Here, the authors show spontaneous generation of gravity waves from the thermal tides in the Venus atmosphere as small-scale gravity waves are resolved in high ...

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.

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.
