Plot the Prague Sky Model sky radiance distribution for the given atmospheric configuration and wavelength.

Parameters:

  • dataset (SkyDataset_Wilkie2021) – Loaded SkyDataset_Wilkie2021 dataset.

  • sun_elevation (float) – Sun elevation at ground level in radians.

  • sun_azimuth (float) – Sun azimuth at ground level in radians.

  • visibility (float) – Meteorological range at ground level in kilometers.

  • albedo (float) – Ground albedo [0, 1].

  • wavelength (float) – Wavelength in nanometers for radiance evaluation.

  • method (Literal['Polar', 'Latlong'] | str) –

    Plotting method:

    • "Polar": Fisheye polar projection (square figure).

    • "Latlong": Latitude-longitude projection (2:1 figure).

  • kwargs (Any) – {colour.plotting.artist(), colour.plotting.render()}, See the documentation of the previously listed definitions.

  • samples (int)

  • epsilon_zenith (float)

  • imshow_kwargs (dict | None)

Returns:

Current figure and axes.

Return type:

tuple
