Far infrared measurements of absorptions by CH4+CO2 and H2+CO2 mixtures and implications for greenhouse warming on early Mars

Martin Turbet, Ha Tran, Olivier Pirali +3

We present an experimental study of the absorption, between 40 and 640 cm${}^{-1}$, by CO${}_2$, CH${}_4$ and H${}_2$ gases as well as by H${}_2$+CO${}_2$ and CH${}_4$+CO${}_2$ mixtures at room te…
