Model description

• Primitive equation system
• Mars atmosphere radiation model
• Turbulent mixing (Mellor and Yamada (1982) level 2.5)
• Surface flux (Beljaars and Holtslag, 1991)
• Simple land model (bucket model, soil heat diffusion)
• Non-convective condensation (Le Treut and Li, 1991)
• Convective adjustment (e.g., Manabe et al., 1965)
• Simple cloud model for Mars (advection, turbulent mixing, and gravitational sedimentation are considered.)
• Dust distribution: MGS scenario (Forget et al., 2001)
• Used data
