内容記述 | The scattering greenhouse effect of CO2 ice cloud has been proposed as a mechanism to make the Martian climate warm enough to support flowing water under a faint young Sun. We construct a one-dimensional radiative model for the CO2-H2O atmosphere and analyze cloud stability on the basis of the numerical estimation of the ice condensation or evaporation rate in a cloud layer. Our numerical analysis suggests that a CO2 ice cloud layer is stabilized and the global mean surface temperature rises above melting point of H2O when the atmospheric pressure is larger than 1 bar and the column number density of cloud condensation nuclei is kept at nearby 10(exp 10) m(exp -2). A negative feedback mechanism between the particle size change and the radiative cooling may stabilize warm climate on early Mars. | |||||
