Detailed Description
A class implementing a primitive surface model.
This is an "invisible" surface processes model which "passes through" information from the atmosphere above directly to the ice below the surface layers. It implements two modeling choices:
- accumulation which is obtained from an atmosphere model is interpreted as surface mass flux;
- mean-annual near-surface air temperature is interpreted as instantaneous temperature of the ice at the ice surface.
The second choice means that the upper boundary condition of the conservation of energy scheme for the ice fluid is exactly the 2m air temperature.
The documentation for this class was generated from the following files:
