  2. Atmosphere of Venus - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Venus

    The troposphere on Venus contains 99% of the atmosphere by mass. 90% of the atmosphere of Venus is within 28 km (17.5 mi) of the surface; by comparison, 90% of the atmosphere of Earth is within 16 km (10 mi) of the surface. At a height of 50 km (31 mi) the atmospheric pressure is approximately equal to that at the surface of Earth. [34]

    Re-analysis of the in situ data gathered by Pioneer Venus Multiprobe in 1978 has also revealed the presence of phosphine and its dissociation products in the atmosphere of Venus. [41] In 2021, a further analysis detected trace amounts of ethane , hydrogen sulfide, nitrite , nitrate , hydrogen cyanide , and possibly ammonia .

    Pyrite, an iron sulfide, matches these criteria and is widely suspected as a possible cause; it would be produced by chemical weathering of the volcanic highlands after long-term exposure to the sulfur-bearing Venusian atmosphere. [8] The presence of pyrite on Venus has been contested, with atmospheric modeling showing that it might not be ...

  8. Atmospheric super-rotation - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_super-rotation

    The initial observations of Venus' super rotation were Earth-based. Modern GCM models and observations are often enhanced by looking at past ancient climates. In a model where Venus is assumed to have an atmospheric mass similar to Earth, SS-AS circulation could have dominated over super-rotation in an ancient thinner atmosphere. [2]
