 Bottom boundary condition of the TKE.\\\\
-'''bc_e_b''' may be set to '' 'neumann' '' or '' '(u*)**2+neumann' ''. '''bc_e_b''' = '' 'neumann' '' yields to e(k=0)=e(k=1) (Neumann boundary condition), where e(k=1) is calculated via the prognostic TKE equation. Choice of '' '(u*)**2+neumann' '' also yields to e(k=0)=e(k=1), but the TKE at the Prandtl-layer top (k=1) is calculated diagnostically by e(k=1)=(us/0.1)**2. However, this is only allowed if a Prandtl-layer is used (#prandtl_layer). If this is not the case, a warning is given and '''bc_e_b''' is reset to '' 'neumann' ''.\\\\

 At the top boundary a Neumann boundary condition is generally used: (e(nz+1) = e(nz)).
