PolarizationChoice

class pyarts.arts.PolarizationChoice(*args, **kwargs)

Group name: “PolarizationChoice”

Named polarization states to help create relevant Stokvec.

Note that these are just user friendly suggestions and it is recommended to create the correct Stokvec manually if the desired polarization state is not represented below.

Also, be aware that the unit of, e.g., spectral_radiance (often the last choice of SpectralRadianceUnitType) is in Kelvin, then the code below will give the measured brightness temperature in Kelvin for these polarization states, but that if the unit is still in Watts of any kind, then the code below will give 2 times the select polarized brightness temperatures (but still the correct unpolarized radiation).

Valid options:

  • "I" or "I": No polarization state [1, 0, 0, 0].

  • "Q" or "Q": Difference between vertical and horizontal linear polarization [0, 1, 0, 0].

  • "U" or "U": Difference between plus and minus 45 degrees linear polarization [0, 0, 1, 0].

  • "V" or "V": Difference between right and left circular polarization [0, 0, 0, 1].

  • "Iv" or "Iv": Vertical linear polarization [1, 1, 0, 0].

  • "Ih" or "Ih": Horizontal linear polarization [1, -1, 0, 0].

  • "Ip45" or "I+45": Plus 45 degrees linear polarization [1, 0, 1, 0].

  • "Im45" or "I-45": Minus 45 degrees linear polarization [1, 0, -1, 0].

  • "Ilhc" or "LC": Left circular polarization [1, 0, 0, -1].

  • "Irhc" or "RC": Right circular polarization [1, 0, 0, 1].

Methods

readxml(self, file: str) None

Read variable from file

Parameters:
