With the Neumann boundary condition the value of the humidity gradient at the top is calculated from the initial humidity profile (see [#q_surface q_surface], [#q_vertical_gradient q_vertical_gradient]) by: bc_q_t_val = ( q_init(k=nz) - q_init(k=nz-1)) / dzu(nz).1422 Allowed are the values '' 'dirichlet' '' (q(k=nz+1) does not change during the run) and '' 'neumann' ''. With the Neumann boundary condition the value of the humidity gradient at the top is calculated from the initial humidity profile (see [#q_surface q_surface], [#q_vertical_gradient q_vertical_gradient]) by: bc_q_t_val = ( q_init(k=nz) - q_init(k=nz-1)) / dzu(nz). 1423 1423 Using this value (assumed constant during the run) the humidity boundary values are calculated as 1424 1424 1425 1425 q(k=nz+1) =q(k=nz) + bc_q_t_val * dzu(nz+1) 1426 1426 1427 (up t pk=nz the prognostic equation for q is solved).\\\\1427 (up to k=nz the prognostic equation for q is solved).\\\\ 1428 1428 In case of nested run the default value of '''bc_q_t''' in the nest domains is not '' 'neumann' '' but '' 'nested' '' instead. For the root domain of a nested run the default is '' 'neumann' '' as usually.\\\\ 1429 1429 }}} … … 1455 1455 {{{#!td 1456 1456 Top boundary condition of the scalar concentration.\\\\ 1457 Allowed are the values '' 'dirichlet' '' (s(k=nz ) and s(k=nz+1) donot change during the run), '' 'neumann' '' (s(k=nz+1) = s(k=nz)), and '' 'initial_gradient' ''. With the '' 'initial_gradient' '' boundary condition the value of the scalar concentration gradient at the top is calculated from the initial scalar concentration profile (see [#s_surface s_surface], [#s_vertical_gradient s_vertical_gradient]) by: bc_s_t_val = (s_init(k=nz) - s_init(k=nz-1)) / dzu(nz).1457 Allowed are the values '' 'dirichlet' '' (s(k=nz+1) does not change during the run), '' 'neumann' '' (s(k=nz+1) = s(k=nz)), and '' 'initial_gradient' ''.
