calculate_polarized_radiance(polarizationtype=None)

Parameters:

polarizationtype : scalar

• 0 - No polarization
• 1 - Exact to scatter order 1
• 2 - Exact to scatter order 2
• 3 - Exact to scatter order 3
• 4 - Exact to scatter order 3, assumes higher orders are strongly polarized
• 5 - Exact to scatter order 4, assumes higher orders are strongly polarized
• 6 - Exact to scatter order 4, assumed higher orders are weakly polarized

Returns:

radiance : numpy array shape (num_los, num_wavel)

wf : numpy array shape(wavelength, line_of_sight, perturbation)

stokes_vector : numpy array shape (num_line_of_sight, num_wavelength) of type StokesVector

calculate_radiance()

Runs the engine and returns back the radiance and weighting functions Weighting functions are only calculated if calcwf is set to something other than 0

Returns:

tuple

(radiance, weighting_function) radiance is of shape (line of sight, wavelength) and weighting_function is of shape (wavelength, line of sight, perturbation) the number and nature of the perturbations is given by the options used to set up the engine
