-The corresponding height levels have to be provided by parameter [#uv_heights uv_heights]. The first velocity value always has to be assigned to the surface and must be zero, i.e. {{{u_profile(1)}}} = 0.0. Velocity values for the model grid levels are calculated from the given values by linear interpolation. If the uppermost value is given for a height smaller than the domain height, this value will be used for all grid points above this level. In runs with non-cyclic horizontal boundary conditions this profile will be used as fixed mean inflow profile.\\\\
+The corresponding height levels have to be provided by parameter [#uv_heights uv_heights]. You need to give values for each of the height levels that are defined via [#uv_heights uv_heights].

 '''Note:''' Simultaneous use of forcing by geostrophic wind is not allowed, since this could lead to inconsistencies in the flow forcing. Hence, [#omega omega] = 0.0 must be set when using '''u_profile''' and [#v_profile v_profile]. The latter flow forcing is typically used for simulating wind-tunnel applications (effect of Coriolis force negligible) in order to fairly reproduce the measured wind-tunnel profiles within the LES.
