nk_f18_blend#

exo_skryer.opacity_cloud.nk_f18_blend(state: Dict[str, Array], params: Dict[str, Array]) → Tuple[Array, Array, Array][source]#

Additive combination of direct_nk and F18 cloud opacity.

Both components share the same vertical cloud profile (q_c_lay from state). The direct_nk component uses the standard node parameters (wl_node_*, n_*, log_10_k_*, log_10_cld_r, cld_rho). The F18 component uses namespaced parameters to avoid collision: log_10_cld_r_f18, cld_rho_f18, cld_Q0, cld_Q1, cld_a.

Extinction is additive. The combined single-scattering albedo and asymmetry parameter are weighted by each component’s scattering opacity (k_ext × ssa), so the result is physically consistent regardless of the relative magnitudes of the two contributions.

Parameters:

statedict: Atmospheric state; must contain wl, q_c_lay, nlay, nwl.
paramsdict: Must contain all direct_nk params plus the F18-namespaced params listed above.

Returns:

k_cldjnp.ndarray, shape (nlay, nwl): Combined cloud extinction coefficient in cm² g⁻¹.
ssajnp.ndarray, shape (nlay, nwl): Combined single-scattering albedo.
gjnp.ndarray, shape (nlay, nwl): Combined asymmetry parameter (flux-weighted over scattering opacities).
