Function Documentation

refr_indexIR()

void refr_indexIR	(	Numeric &	refr_index,
		const Numeric &	rte_pressure,
		const Numeric &	rte_temperature,
		const Vector &	rte_vmr_list,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: refr_indexIR.

Calculates the IR refractive index due to gases in the Earth's atmosphere.

Only refractivity of dry air is considered. The formula used is contributed by Michael Hoefner, Forschungszentrum Karlsruhe.

[out]	refr_index	WS Output
[in]	rte_pressure	WS Input
[in]	rte_temperature	WS Input

refr_indexThayer()

void refr_indexThayer	(	Numeric &	refr_index,
		const Numeric &	rte_pressure,
		const Numeric &	rte_temperature,
		const Vector &	rte_vmr_list,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: refr_indexThayer.

Calculates the microwave refractive index due to gases in the Earth's atmosphere.

The refractivity of dry air and water vapour is summed. All other gases are assumed to have a negligible contribution.

The parameterisation of Thayer (Radio Science, 9, 803-807, 1974) is used. See also Eq. 3 and 5 of Solheim et al. (JGR, 104, pp. 9664).

refr_indexUnit()

void refr_indexUnit	(	Numeric &	refr_index,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: refr_indexUnit.

Sets the refractive index to 1.

If this method is used, the obtained path should be identical to the geomtrical path.
