cppvdisort

class pyarts3.arts.cppvdisort(*args, **kwargs)

A low-level polarized VDISORT object.

The calling style mirrors cppdisort, but scalar phase coefficients, boundary values, sources, and beam intensity are replaced by their polarized counterparts. Stokes components are ordered [I, Q, U, V].

phase_matrix has shape [2, NFourier, NLayers, NQuad, NQuad, 4, 4]. The leading dimension contains the combined cosine and sine equations. b_pos and b_neg have shape [2, NFourier, NQuad/2, 4] and s_poly_coeffs has shape [NLayers, Ncoeffs, 4]. Its coefficients are the Stokes source function B = [B_I, B_Q, B_U, B_V]; VDISORT applies the layer factor 1 - omega internally. An unpolarized source is therefore supplied as [B, 0, 0, 0].

Methods

flux(self, tau: pyarts3.arts.AscendingGrid) → pyarts3.arts.Matrix: Compute Stokes-I upward, downward-diffuse, downward-direct flux and DFDT

has_complex_eigensolutions(self, tolerance: float = 1e-12) → bool: Return whether any retained transport eigenvalue is significantly complex

pydisort_u(self, tau: pyarts3.arts.Vector, phi: pyarts3.arts.Vector) → pyarts3.arts.Tensor4: Compute Stokes radiance with shape [stream, tau, phi, stokes]

u(self, tau: pyarts3.arts.AscendingGrid, phi: pyarts3.arts.Vector) → pyarts3.arts.Tensor4: Compute the Stokes radiance with shape [tau, phi, stream, stokes]

u_user(self, tau: pyarts3.arts.AscendingGrid, phi: pyarts3.arts.Vector, mu: pyarts3.arts.Vector, phase_matrix: pyarts3.arts.MuelmatTensor5, beam_phase_matrix: pyarts3.arts.MuelmatTensor4 | None = None) → pyarts3.arts.StokvecTensor3

Compute Stokes radiance at arbitrary nonzero polar-angle cosines.

The phase arrays contain the combined cosine/sine Mueller coefficients sampled at the requested outgoing directions. Their numerical shapes are [2, NFourier, NLayers, NUser, NQuad, 4, 4] and [2, NFourier, NLayers, NUser, 4, 4] for the direct beam.
