     1867With a constant flux layer switched on (see [#constant_flux_layer constant_flux_layer]), the Obukhov length ('''ol''') is calculated for {{{z=z_mo (k=1)}}} in the 3d-model (in the [../../tec/1dmodel 1d-model] for all heights) for each horizontal grid point. Its particular values determine the values of the friction velocity (1d- and 3d-model) and the values of the eddy diffusivity (1d-model). With small wind velocities at the top of the constant flux layer or small vertical wind shears in the 1d-model, the stability parameter '''zeta = z_mo/ol''' can take up unrealistic values. They are limited by an upper ('''zeta_max''') and lower limit (see [#zeta_min zeta_min]). The condition '''zeta_max''' > zeta_min must be met.
