Python Result Classes

DisortResult

Returned by DisortSolver.solve(). Contains all computed radiant quantities.

Flux vectors

All flux attributes are Python lists (convertible to NumPy arrays). Size is num_user_tau (or num_layers + 1 when use_user_tau = False).

Attribute	Description
flux_direct_beam	Direct-beam flux.
flux_down	Diffuse downward flux.
flux_up	Diffuse upward flux.
flux_tau_divergence	Flux divergence.
mean_intensity	Mean intensity (including direct beam).
mean_intensity_down	Mean diffuse downward intensity.
mean_intensity_up	Mean diffuse upward intensity.
mean_intensity_direct_beam	Mean direct beam intensity.

Special boundary condition mode

Attribute	Description
albedo_medium	Medium albedo at each user angle.
transmissivity_medium	Medium transmissivity at each user angle.
spherical_albedo	Spherical albedo (scalar).
spherical_transmissivity	Spherical transmissivity (scalar).

Intensity arrays

Attribute	Description
mu_angles	Polar angle cosines for intensity output.
intensity	3D nested list [tau][mu][phi].
intensity_azimuth_avg	2D nested list [tau][mu].
intensity_fourier_expansion	3D nested list [tau][mu][fourier term].

Convert to NumPy for convenient indexing:

intensity = np.array(result.intensity)
# intensity.shape == (num_user_tau, num_user_mu, num_phi)

flux_up = np.array(result.flux_up)
# flux_up.shape == (num_user_tau,)

Methods

result.num_user_tau()

Number of output levels.

result.num_user_mu()

Number of output polar angles.

result.num_phi()

Number of azimuthal angles.

result.total_flux_down(lu)

Total downward flux at output level lu (direct + diffuse).

result.net_flux(lu)

Net flux at output level lu (downward positive).

result.intensities(iu, lu, j)

Access the 3D intensity at user angle iu, level lu, azimuth j. Indices are 0-based.

result.intensities_azimuth_avg(iu, lu)

Access the azimuthally-averaged intensity. Indices are 0-based.

FluxResult

Returned by DisortFluxSolver.solve(). Lightweight flux-only container.

All vectors have size num_layers + 1 (index 0 = TOA, last = BOA).

Attribute	Description
flux_direct_beam	Direct-beam flux at each level.
flux_down	Diffuse downward flux at each level.
flux_up	Diffuse upward flux at each level.
flux_tau_divergence	Flux divergence at each level.
mean_intensity	Mean intensity at each level.
mean_intensity_down	Mean diffuse downward intensity.
mean_intensity_up	Mean diffuse upward intensity.
mean_intensity_direct_beam	Mean direct beam intensity.

Methods

result.num_levels()

Number of output levels.

result.total_flux_down(lev)

Total downward flux at level lev.

result.net_flux(lev)

Net flux at level lev.
