+Factor for calculating a roughness length for scalars.\\\\
+A separated roughness length for scalars (potential temperature, humidity/scalar) can be set with this parameter. The roughness length for scalars z0h is calculated as: \\
+      z0h = z0h_factor * [#roughness_length roughness_length]. \\
+This parameter is effective only in case that a Prandtl layer is switched on (see [#prandtl_layer prandtl_layer]).
