Detailed Description

Implementation file for work with HITRAN collision induced absorption (CIA).

The CIA data are part of the HITRAN distribution. They are described in Richard, C., I. E. Gordon, L. S. Rothman, M. Abel, L. Frommhold, M. Gustafsson, J.-M. Hartmann, C. Hermans, W. J. Lafferty, G. S. Orton, K.M. Smith, and H. Tran (2012), New section of the HITRAN database: Collision-induced absorption (CIA), J. Quant. Spectrosc. Radiat. Transfer, 113, 1276-1285, doi:10.1016/j.jqsrt.2011.11.004.

cia_get_data()

std::shared_ptr< CIARecord > cia_get_data	(	const std::vector< std::shared_ptr< CIARecord > > &	cia_data,
		const Species::Species	sp1,
		const Species::Species	sp2
	)

Get the correct cia recrod.

Parameters

[in]	cia_data	CIA data array
[in]	sp1	First species index
[in]	sp2	Second species index

Returns

Correct CIA record or nullptr if not found.

cia_get_index()

Index cia_get_index	(	const ArrayOfCIARecord &	cia_data,
		const Species::Species	sp1,
		const Species::Species	sp2
	)

Get the index in cia_data for the two given species.

Parameters

[in]	cia_data	CIA data array
[in]	sp1	First species index
[in]	sp2	Second species index

Returns

Index of this species combination in cia_data. -1 if not found.

cia_interpolation()

void cia_interpolation	(	VectorView	result,
		const ConstVectorView &	f_grid,
		const Numeric &	temperature,
		const GriddedField2 &	cia_data,
		const Numeric &	T_extrapolfac,
		const Index &	robust,
		const Verbosity &	verbosity
	)

Interpolate CIA data.

Interpolate CIA data to given frequency vector and given scalar temperature. Uses third order interpolation in both coordinates, if grid length allows, otherwise lower order or no interpolation.

Parameters

[out]	result	CIA value for given frequency grid and temperature.
[in]	f_grid	Frequency grid.
[in]	temperature	Scalar temperature.
[in]	cia_data	The CIA dataset to interpolate.
[in]	robust	Set to 1 to suppress runtime errors (and return NAN values instead).
[in]	verbosity	Standard verbosity object.

operator<<()

ostream & operator<<	(	ostream &	os,
		const CIARecord &	cr
	)

Output operator for CIARecord.

Outputs the grids for the given CIARecord.

Parameters

[in,out]	os	Output stream.
[in]	cr	CIARecord.

Returns

os
