Nighttime Convection by Water-Ice Clouds on Mars
Résumé
Recently, Martian water ice clouds have been acknowledged to play an even more central role in Mars’ meteorology and climate. Their infrared absorption and emission overwhelm their diffusive and absorbing role in the visible , thereby warming the daytime upper tro- posphere of Mars and most significantly cooling the atmosphere and warming the surface in the night (up to +25 K) . This causes the strong temperature inversions in radiooccultation profiles obtained on board Mars Global Surveyor . Global Climate Modeling showed that the radiative effect of clouds plays an essential role in the global thermal structure and dynamics of the Martian atmosphere.
