pyrt.make_hapkeHG2_surface(user_angles, only_fluxes, n_polar, n_azimuth, n_streams, mu, mu0, phi, phi0, beam_flux, n_mug, b0, h, w, asym, frac)[source]#

Make a 2-lobed Henyey-Greenstein Hapke surface.

Parameters:

  • user_angles (bool) – True if this should be returned at user angles; False otherwise.

  • only_fluxes (bool) – True of only fluxes should be returned; False otherwise. Note that I don’t know why this would be relevant to this function, but DISORT requires it.

  • n_polar (int) – The number of polar angles.

  • n_azimuth (int) – The number of azimuth angles.

  • n_streams (int) – The number of streams.

  • mu (float) – The cosine of emission.

  • mu0 (float) – The cosine of incidence.

  • phi (float) – The azimuth angle.

  • phi0 (float) – Phi0

  • beam_flux (float) – The incident beam flux.

  • n_mug (int) – The number of angle quadrature points.

  • b0 (float) – The strength of the opposition surge.

  • h (float) – The width of the opposition surge.

  • w (float) – The surface single scattering albedo.

  • asym (float) – The asymmetry parameter (b)

  • frac (float) – The forward scattering fraction (c)

Returns:

The arguments to apply to disobrdf.

Return type:

list

Notes

The output of this function can be easily piped into disort.disobrdf with disort.disobrdf(*make_hapkeHG2_surface(<args>)).
