Sublimation of the Martian CO2 seasonal South Polar Cap.
International audience The polar condensation/sublimation of CO2, that involve about one fourth of the atmosphere mass,is the major Martian climatic cycle.Early observations in visible and thermal infrared have shown that the sublimation of the Seasonal South Polar Cap (SSPC) is not symmetric around...
