Add the Harvey et al. (1998) water/steam refractivity to single_dispersion.

The model covers the real refractive index in the visible and near infrared. The added value is \(n-1\), matching the convention consumed by ray_point_back_propagation_agenda when it uses its RefractiveStepwise option.

By default, the water mass density is derived from the H2O VMR, pressure, temperature, and isotopologue masses in atm_point. Set water_mass_density to a non-negative value to use an explicit density instead. An explicit value is useful for liquid-water calculations.

This method only contributes refractivity. 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]

  • freq (Numeric, optional) – A single frequency. Unit: Hz. See freq, defaults to self.freq [IN]

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

  • water_mass_density (Numeric, optional) – Water mass density [kg/m3]. A negative value derives it from the H2O VMR in atm_point. Defaults to -1 [IN]

  • check_validity (Index, optional) – Enforce the published temperature, density, and wavelength validity ranges. Defaults to 1 [IN]
