Mars experiment

Model

• dcpam5 development version around 2015/11/25
  • roughly correspond to dcpam5-20160110

• A following option is given at compilation
  • -DSLTT2D1DMONOTONIC

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.)
