Common 0.1 bar tropopause in thick atmospheres set by pressure-dependent infrared transparency
In many planetary atmospheres, including that of Earth, the base of the stratosphere—the tropopause—occurs at an atmospheric pressure of 0.1 bar. A physically based model demonstrates that the pressure-depende...

Alteration Assemblages in Martian Meteorites: Implications for Near-Surface Processes
The SNC (Shergotty-Nakhla-Chassigny) meteorites have recorded interactions between martian crustal fluids and the parent igneous rocks. The resultant secondary minerals — which comprise up to ∼1 vol.% of the m...

Western boundary currents in the atmosphere of Mars
WESTERN boundary currents (WBCs) are an intensification of north–south flow adjacent to an eastward-facing meridional boundary. Although most familiar in the oceans (where the Gulf Stream is the best known exa...
