Workspace.single_dispersionAddGasMicrowavesGeneral(self, single_dispersion: pyarts3.arts.Numeric | None = None, atm_point: pyarts3.arts.AtmPoint | None = None) → None

Add microwave gas refractivity for a planetary atmosphere.

This is the non-dispersive Newell and Baird (1965) mixture model used by ARTS 2. It supports N2, O2, CO2, H2, He, and H2O. Every species is optional: only supported species present in atm_point contribute. Their VMRs are normalized by the sum of the supported VMRs that are present. If none are present, the method adds zero refractivity.

Reference refractivities are scaled from 273.15 K and 760 Torr to the pressure and temperature in atm_point. The added value is \(n-1\), matching the convention consumed by ray_point_back_propagation_agenda with its RefractiveStepwise option.

This method contributes refractivity only. It does not add absorption to single_propmat or derivatives to single_dispersion_jac.

Parameters:

  • single_dispersion (Numeric, optional) – A dispersion at a single freq point. See single_dispersion, defaults to self.single_dispersion [INOUT]

  • atm_point (AtmPoint, optional) – An atmospheric point in ARTS. See atm_point, defaults to self.atm_point [IN]
