science communities came together at a November 2011 workshop held at the European Space Agency's (ESA) European Space Research and Technology Centre ( ESTEC) site in the Netherlands to discuss the nature of waves observed in Venus's atmosphere and their comparison to those on Earth and Mars....
The composition of Venus’s atmosphere is well known, and is likely being replenished by volcanic gases. Analysis suggests that the volcanic eruptions are water-poor — implying that the planet’s mantle is dry. This is consistent with Venus having had a long-lasting dry surface and never hav...
Atmospheric circulation refers to the patterns of air movement from one location to another and from the surface to higher elevations in Earth's atmosphere. These patterns are influenced by various factors such as Earth's rotation, barometric pressure, topography, and ocean currents. The circulation...
Fig. 15. Impact of turbulence on the body normal line defined in Fig. 14 for the 30 km altitude case. A similar comparison is made in Figs. 16 and 17 for the lower-pressure 50 km altitude case studied in previous sections. For this case, up to a 40% increase is seen for the...

inorganic phosphate. These compounds could conceivably have been brought in by comets or asteroids (Chyba et al.1989,1990) or micrometeorites (Maurette et al.2000), or they could have been formed in situ on the early Earth. Here, we estimate the rate of formation of these compounds on the...
Venus lost its water by hydrodynamic escape, Earth lost CO_2 that formed carbonates and is strongly affected by life. Mars lost water in the reaction with iron and then most of the atmosphere by the intense meteorite impacts. (2) In spite of the higher solar radiation on Venus, its ...
Atmospheric Escape From TOI-700 d: Venus versus Earth AnalogsDong, C.Jin, M.Lingam, M.LPI Contribution
EarthImpact processesMars atmosphereVenus atmosphereThe atmospheres of the terrestrial planets are known to have been modified as a consequence of the impact degassing and atmospheric erosion during the late accretion. Despite the commonality of these processes, there are distinct gaps - roughly two ...
