RoughLMomSnow

Roughness length for momentum above snow. Used as z_0M in (4.14) but for snow surface. Used only if the surface energy is calculated by solving the energy balance at the surface. If a canopy is present, the roughness length for snow is only used if the Switch "SnowRoughness" is set to Individual.

SThermalCondCoef

Thermal conductivity coefficient for snow.

Default	Unit	Symbol	Equation	Function
2.86E-6	W m⁵°C^-1kg^-2	s_k	(4.50)	Thermal Conductivity of Snow

The normal value 2.86E-6 (W m⁵ °C^-1 kg^-2) implies the thermal conductivity function for snow is valid in a range of density from 100 to 900 kg/m3. The highest density corresponds to pure ice. A square dependence of the snow density is assumed in the whole range.
