Radiative-convective model of warming Mars with artificial greenhouse gases

Influence of Greenhouse Gases to Global Warming on Account of Radiative Forcing

Sulfur - Related Greenhouse Warming on Early Mars

Introduction: A building body of evidence from recent Mars exploration missions suggests that sulfur chemistry may have played a prominent role in the planet’s early evolution. Although the Martian atmosphere contains virtually no sulfur species at present, both soils and outcrop observed by landed missions have high sulfate abundances [1,2]. The OMEGA hyperspectral imager has now also identifi...

Transient reducing greenhouse warming on early Mars

The evidence for abundant liquid water on early Mars despite 3 the faint young Sun is a long-standing problem in planetary research. Here 4 we present new ab initio spectroscopic and line-by-line climate calculations 5 of the warming potential of reduced atmospheres on early Mars. We show 6 that the strength of both CO2-H2 and CO2-CH4 collision-induced absorp7 tion (CIA) has previously been sig...

Sulfur-induced greenhouse warming on early Mars

[1] Mineralogical, geological, geophysical, and isotopic data recently returned from Mars suggest that the delivery of sulfur gases to the atmosphere may have played a significant role in the planet’s early evolution. Using the Gusev Crater basalt composition and a batch melting model, we obtain a high sulfur solubility, approximately 1400 ppm, in Martian mantle melts. We proceed to explore dif...

Keeping Mars warm with new super greenhouse gases.

Our selection of new super greenhouse gases to fill a putative "window" in a future Martian atmosphere relies on quantum-mechanical calculations. Our study indicates that if Mars could somehow acquire an Earth-like atmospheric composition and surface pressure, then an Earth-like temperature could be sustained by a mixture of five to seven fluorine compounds. Martian mining requirements for repl...
