- Two factors control the vertical structure of the lower atmosphere—its composition of almost pure carbon dioxide and its content of large quantities of suspended dust. Because carbon dioxide radiates energy efficiently at Martian temperatures, the atmosphere can respond rapidly to changes in the amount of solar radiation received.

1 day ago · Global circulation models, which incorporate all the factors understood to influence the behavior of the atmosphere, predict a strong dependence of winds on the Martian seasons because of the large horizontal temperature gradients associated with the edge of the polar caps in the fall and winter.
Feb 2, 2023 · Spacecraft observations and climate modelling have revealed how atmospheric waves, dust storms and atmospheric loss processes are coupled throughout the atmosphere of Mars.
Jul 5, 2024 · We think atmospheric oxidation led to Mars becoming cold and bipolar in its early history. The study reveals anoxic leaching in ancient Martian terrains occurred during seasonal freeze-thaw...
3 days ago · The atmosphere is very thin, exerting less than 1 percent of Earth’s atmospheric pressure at the surface. Surface pressures range over a factor of 15 because of the large altitude variations in Mars’s topography. Only small amounts of water are present in the atmosphere today.
Sep 17, 2023 · Mars atmosphere composition. According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface...
