Stability of CO2 ice clouds and scattering greenohouse effect on early Martian wet atmosphere

Abstract

In order to investigate scattering greenhouse effect of CO₂ ice clouds and those stability against radiative heating on a CO₂-H₂O atmosphere, we constructed a one-dimensional, radiative-convective model. The our calculations suggest that warm and wet climate is possibly induced by the stable cloud layer with visible optical depth about 1.5 when the atmospheric pressure and the radius of cloud particles are fixed 1 atm and 10 micron, respectively.
