Interface to the DISORT scattering solver (by Stamnes et al.). for running clear-sky cases.

The method runs DISORT with pnd_field set to zero.

Note that this version returns spectral_radiance_field, i.e. the solution for the full atmosphere. The standard cloudbox_fieldDisort() only returns the field inside the cloudbox.

Some auxiliary quantities can be obtained. Auxiliary quantities are selected by disort_aux_vars and returned by disort_aux. Valid choices for auxiliary data are:

  • "Layer optical thickness": Matrix [f_grid, size of p_grid - 1] layer optical thickness.

  • "Single scattering albedo": Matrix [f_grid, size of p_grid - 1] layer single scattering albedo.

  • "Asymmetry parameter": Matrix [f_grid, size of p_grid - 1] layer asymmetry parameter.

  • "Direct downward spectral irradiance": Matrix [f_grid, p_grid]. Direct downward spectral irradiance. Zero, if no sun is present.

  • "dFdtau": Matrix [f_grid, p_grid]. Flux divergence in optical thickness space.
