 If a non-zero value is assigned to this parameter, the respective scalar flux value is used as bottom (horizontally homogeneous) boundary condition for the scalar concentration equation. This additionally requires that a Neumann condition must be used for the scalar concentration (see [#bc_s_b bc_s_b]), because otherwise the resolved scale may contribute to the surface flux so that a constant value cannot be guaranteed. Also, changes of the surface scalar concentration (see [#s_surface_initial_change s_surface_initial_change]) are not allowed.\\\\
 If no surface scalar flux is assigned ('''surface_scalarflux''' = ''0.0''), it is calculated at each time step by u,,*,, {{{*}}} s,,*,, (of course only with [#constant_flux_layer constant_flux_layer] switched on). Here, s,,*,, is calculated from Monin-Obukhov similarity theory assuming a logarithmic scalar concentration profile between k=0 and k=1. In this case, a Dirichlet condition (see bc_s_b) must be used as bottom boundary condition for the scalar concentration.

 If a value is assigned to this parameter, the internal two-dimensional surface scalar flux field {{{sswst}}} is initialized with the value of '''top_scalarflux''' as the top (horizontally homogeneous) boundary condition for the scalar equation. This additionally requires that a Neumann condition must be used for the scalar (see [#bc_s_t bc_s_t]), because otherwise the resolved scale may contribute to the top flux so that a constant flux value cannot be guaranteed.\\\\

+Scalar concentration gradient(s) of the initial scalar concentration profile (in kg / 100 m).\\\\
 The scalar gradient holds starting from the height level defined by [#s_vertical_gradient_level s_vertical_gradient_level] (precisely: for all uv levels k, where zu(k) > s_vertical_gradient_level, s_init(k) is set: s_init(k) = s_init(k-1) + dzu(k) * '''s_vertical_gradient''') up to the top boundary or up to the next height level defined by s_vertical_gradient_level. A total of 10 different gradients for 11 height intervals (10 intervals if s_vertical_gradient_level(1) = 0.0) can be assigned. The surface scalar value is assigned via [#s_surface s_surface].\\\\

       '''s_vertical_gradien'''t = ''0.1,'' ''0.05,''\\
