Mars Atmosphere-Ice Coupler MAIC-2


The Mars Atmosphere-Ice Coupler MAIC-2 is a simple, latitudinal model that consists of a set of parameterisations for the surface temperature, the atmospheric water transport and the surface mass balance (condensation minus evaporation) of water ice. It is driven directly by orbital parameters. A detailed description of the model is given by Greve et al. (2010, 2012).

The model equations of MAIC-2 are discretised by a finite-difference/finite-volume scheme. Coding is done in the programming language Fortran 90.

Required model forcing
(as functions of time):

  • Obliquity (axial tilt).
  • Orbital eccentricity.
  • Solar longitude (Ls)
    of perihelion.

Output (as functions of latitude and time):

  • Surface temperature.
  • Evaporation rate of water ice.
  • Condensation rate of water ice.
  • Atmospheric water content.
  • Surface mass balance of water ice.
  • Ice thickness.
