Arguments
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| class(ty_optical_props_arry), | intent(in) | :: | optical_props | Set of optical properties as one or more arrays |
||
| logical, | intent(in) | :: | top_at_1 | Is the top of the domain at index 1? (if not, ordering is bottom-to-top) |
||
| type(ty_source_func_lw), | intent(in) | :: | sources | Derived type with Planck source functions |
||
| real(kind=wp), | intent(in), | dimension(:,:) | :: | sfc_emis | emissivity at surface [] (nband, ncol) |
|
| class(ty_fluxes), | intent(inout) | :: | fluxes | Dervied type for computing spectral integrals from g-point fluxes. Default computes broadband fluxes at all levels if output arrays are defined. Can be extended per user desires. |
||
| real(kind=wp), | intent(in), | optional | dimension(:,:), target | :: | inc_flux | incident flux at domain top [W/m2] (ncol, ngpts) |
| integer, | intent(in), | optional | :: | n_gauss_angles | Number of angles used in Gaussian quadrature (max 3, no-scattering solution) |
|
| logical, | intent(in), | optional | :: | use_2stream | When 2-stream parameters (tau/ssa/g) are provided, use 2-stream methods Default is to use re-scaled longwave transport |
|
| real(kind=wp), | intent(in), | optional | dimension(:,:) | :: | lw_Ds | User-specifed 1/cos of transport angle per col, g-point |
| real(kind=wp), | intent(inout), | optional | dimension(:,:), target | :: | flux_up_Jac | surface temperature flux Jacobian [W/m2/K] (ncol, nlay+1) |
