Configure single_propmat_agenda for Earth microwave gas refraction.

The agenda initializes all single-frequency propagation quantities and adds the Earth microwave gas refractivity. Pair it with ray_point_back_propagation_agendaSet(option="RefractiveStepwise") and a frequency-dependent propagation method such as spectral_radClearskyEmissionFrequencyDependentPropagation().

The resulting agenda contains no absorption model. Build a custom single_propmat_agenda when absorption and refraction are both needed.

Parameters:

  • single_propmat_agenda (~pyarts3.arts.Agenda, optional) – Computes the propagation matrix, the non-LTE source vector, the dispersion, and their derivatives. Defaults to self.single_propmat_agenda. [OUT]

  • k1 (~pyarts3.arts.Numeric, optional) – Dry-air coefficient [K/Pa]. Defaults to 7.76e-07 [IN]

  • k2 (~pyarts3.arts.Numeric, optional) – Water-vapour coefficient [K/Pa]. Defaults to 7.04e-07 [IN]

  • k3 (~pyarts3.arts.Numeric, optional) – Water-vapour coefficient [K^2/Pa]. Defaults to 0.003739 [IN]
