    15461546When a constant surface sensible heat flux is used ([#surface_heatflux surface_heatflux]), '''bc_pt_b''' = '' 'neumann' '' must be used, because otherwise the resolved scale may contribute to the surface flux so that a constant value cannot be guaranteed.\\\\
    15471547In the coupled atmosphere executable, '''bc_pt_b''' is internally set and does not need to be prescribed.

    23912391Instead of prescribing a [#surface_heatflux surface_heatflux] also a surface heating rate can be prescribed by setting '''pt_surface_heating_rate''' to a non-zero value. Surface cooling can be achieved by assigning a negative value.\\
