Value

Meaning

Uniform temperature

A parameter SoilInitTempConst is used to calculate the initial heat storage.

Temp(z)-Table

A parameter table InitialTemperatures is used to assign values of initial temperature at different layers for estimation of initial heat storage.

Temp(z)-Estimated

A temperature profile is taken from the analytical solution of the sine variation at the soil surface and a mean value of damping depth for the whole soil profile.

Heat(z)

A parameter table InitialHeatStorages is used to assign values of initial values for all heat state variable. Note that heat is defined relative to the level of non-frozen water at 0 ºC.
