◆ abs_coefCalc()

void abs_coefCalc	(	Matrix &	abs_coef,
		ArrayOfMatrix &	abs_coef_per_species,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Vector &	f_grid,
		const Vector &	abs_p,
		const Vector &	abs_t,

		const ArrayOfString &	abs_cont_models,
		const ArrayOfVector &	abs_cont_parameters,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_coefCalc.

Calculate absorption coefficients.

This function calculates both the total absorption (abs_coef), and the absorption per species (abs_coef_per_species).

The method calls four other methods:

abs_xsec_per_speciesInit: Initialize abs_xsec_per_species
abs_xsec_per_speciesAddLines: Calculate cross sections per tag group for line spectra.
abs_xsec_per_speciesAddConts: Calculate cross sections per tag group for continua.
abs_coefCalcFromXsec: Calculate absorption coefficients from the cross sections by multiplying each cross section by n*VMR.

This is done once for each tag group (output abs_coef_per_species), and for the sum of all tag groups (output abs_coef).

	)

WORKSPACE METHOD: abs_coefCalcSaveMemory.

Calculate absorption coefficients, trying to conserve memory.

This function calculates only the total absorption (abs_coef), NOT the absorption per tag group (abs_coef_per_species).

This means you cannot use it if you want to calculate Jacobians later.

The implementation follows abs_coefCalc.

		const String &	tagname,
		const String &	model,
		const Vector &	userparameters,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_cont_descriptionAppend.

Appends the description of a continuum model or a complete absorption model to abs_cont_names and abs_cont_parameters.

See online documentation for abs_cont_names for a list of allowed models and for information what parameters they require. See file includes/continua.arts for default parameters for the various models.

void abs_cont_descriptionInit	(	ArrayOfString &	abs_cont_names,
		ArrayOfString &	abs_cont_models,
		ArrayOfVector &	abs_cont_parameters,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_cont_descriptionInit.

Initializes the two workspace variables for the continuum description, abs_cont_names* and abs_cont_parameters.

This method does not really do anything, except setting the two variables to empty Arrays. It is just necessary because the method abs_cont_descriptionAppend* wants to append to the variables.

Formally, the continuum description workspace variables are required by the absorption calculation methods (e.g., abs_coefCalc). Therefore you always have to call at least abs_cont_descriptionInit, even if you do not want to use any continua.

[out]	abs_cont_names	WS Output
[out]	abs_cont_models	WS Output
[out]	abs_cont_parameters	WS Output

void abs_h2oSet	(	Vector &	abs_h2o,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Matrix &	abs_vmrs,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_h2oSet.

Sets abs_h2o to the profile of the first tag group containing water.

This is necessary, because for example abs_coefCalc requires abs_h2o to contain the water vapour profile(the reason for this is the calculation of oxygen line broadening requires water vapour profile). Then this function can be used to copy the profile of the first tag group of water.

	)

WORKSPACE METHOD: abs_lines_per_speciesAddMirrorLines.

Adds mirror lines at negative frequencies to abs_lines_per_species.

	)

WORKSPACE METHOD: abs_lines_per_speciesCreateFromLines.

Split lines up into the different species.

The species are tested in the order in which they are specified in the controlfile. Lines are assigned to the first species that matches. That means if the list of species is ["O3-666","O3"], then the last group O3 gets assigned all the O3 lines that do not fit in the first group (all other isotopes than the main isotope).

		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const ArrayOfString &	filenames,
		const ArrayOfString &	formats,
		const Vector &	fmin,
		const Vector &	fmax,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lines_per_speciesReadFromCatalogues.

Read spectral line data from different line catalogues.

For each absorption species, you can specify which catalogue to use. Because the method creates abs_lines_per_species directly, it replaces for example the following two method calls:

- abs_linesReadFromHitran - abs_lines_per_speciesCreateFromLines

This method needs as input WSVs the list of species abs_species*. Generic input parameters must specify the names of the catalogue files to use and the matching formats. Names can be anything, formats can currently be HITRAN96 (for HITRAN 1986-2001 databases), HITRAN04 (for HITRAN 2004 database), MYTRAN2, JPL, or ARTS. Furthermore, you have to specify minimum and maximum frequency for each species. To safe typing, if there are less elements in the keyword parameters than there are species, the last parameters are applied to all following species.

Example usage:

abs_lines_per_speciesReadFromCatalogues( [ "../data/cat1.dat", "../data/cat2.dat" ] [ "MYTRAN2", "HITRAN96" ] [ 0, 0 ] [ 2000e9, 100e9 ] )

In this example, lines for the first species will be taken from cat1, lines for all other species will be taken from cat2. This allows you for example to use a special line file just for water vapor lines.

Catalogues are only read once, even if several tag groups have the same catalogue. However, in that case the frequency ranges MUST be the same. (If you want to do fine-tuning of the frequency ranges, you can do this inside the tag definitions, e.g., "H2O-*-0-2000e9".)

This function uses the various reading routines (abs_linesReadFromHitran, etc.), as well as abs_lines_per_speciesCreateFromLines*.

WORKSPACE METHOD: abs_lines_per_speciesSetEmpty.

Sets abs_lines_per_species to empty line lists.

You can use this method to set abs_lines_per_species if you do not really want to compute line spectra. Formally, abs_coefCalc will still require abs_lines_per_species to be set.

		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lineshape_per_tgDefine.

Set the lineshape, separately for each absorption species.

This method is similar to abs_lineshapeDefine, except that a different lineshape can be set for each absorption species (see abs_species*). For example, you might want to use different values of the cutoff frequency for different species.

void abs_lineshapeDefine	(	ArrayOfLineshapeSpec &	abs_lineshape,
		const String &	shape,
		const String &	normalizationfactor,
		const Numeric &	cutoff,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lineshapeDefine.

Set the lineshape for all calculated lines.

Sets the lineshape function. Beside the lineshape function itself, you also have so select a forefactor and a frequency cutoff. The forefactor is later multiplied with the lineshape function.

The cutoff frequency is used to make lineshapes finite in frequency, the response outside the cutoff is set to zero, and the lineshape value at the cutoff frequency is subtracted from the overall lineshape as a constant offset. This ensures that the lineshape goes to zero at the cutoff frequency without a discontinuity.

We generate only one copy of the lineshape settings. Absorption routines check for this case and use it for all species.

The allowed values for the input parameters are:

shape: no_shape: no specified shape Doppler: Doppler lineshape Lorentz: Lorentz lineshape Voigt_Kuntz3: Kuntz approximation to the Voigt lineshape, accuracy > 2x10^(-3) Voigt_Kuntz4: Kuntz approximation to the Voigt lineshape, accuracy > 2x10^(-4) Voigt_Kuntz6: Kuntz approximation to the Voigt lineshape, accuracy > 2x10^(-6) Voigt_Drayson: Drayson approximation to the Voigt lineshape Rosenkranz_Voigt_Drayson: Rosenkrantz oxygen absortion with overlap correction on the basis of Drayson routine Rosenkranz_Voigt_Kuntz6 : Rosenkrantz oxygen absortion with overlap correction on the basis of Kuntz routine, accuracy > 2x10^(-6) CO2_Lorentz: Lorentz multiplied with Cousin's chi factors CO2_Drayson: Drayson multiplied with Cousin's chi factors

forefactor: no_norm: 1 quadratic: (f/f0)^2 VVH: (f*tanh(h*f/(2k*T))) / (f0*tanh(h*f0/(2k*T)))

cutoff: -1: no cutoff <Number>: positive cutoff frequency in Hz

		const Numeric &	rte_doppler,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_scalar_gasCalcLBL.

Calculates scalar gas absorption coefficients line-by-line.

This method can be used inside abs_scalar_gas_agenda just like abs_scalar_gasExtractFromLookup*. It is a shortcut for putting in some other methods explicitly, namely:

1. f_gridSelectFIndex 2. NumericScale( rte_doppler, rte_doppler, -1 ) 3. VectorAddScalar( f_grid, f_grid, rte_doppler ) 4. AbsInputFromRteScalars 5. abs_h2oSet 6. abs_coefCalc 7. abs_scalar_gasFromAbsCoef

Sub-methods 2 and 3 are called only if rte_doppler is not zero. The treatment of the Doppler-shift here is exact, since the underlying frequency grid is shifted.

The calculation is for one specific atmospheric condition, i.e., a set of pressure, temperature, VMR values, and Doppler shift. It can be either for a single frequency (f_index>=0), or for all frequencies (f_index<0). The dimension of the output abs_scalar_gas is adjusted accordingly.

WORKSPACE METHOD: abs_speciesDefineAllInScenario.

Define one tag group for each species known to ARTS and included in an atmospheric scenario.

		const Vector &	rte_vmr_list,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: AbsInputFromRteScalars.

Initialize absorption input WSVs from local atmospheric conditions.

The purpose of this method is to allow an explicit line-by-line calculation, e.g., by abs_coefCalc, to be put inside the abs_scalar_gas_agenda*. What the method does is to prepare absorption input parameters (pressure, temperature, VMRs), from the input parameters to abs_scalar_gas_agenda. There is a matching method to turn the output of abs_coefCalc into what the agenda expects (abs_scalar_gasFromAbsCoef).

◆ f_gridSelectFIndex()

void f_gridSelectFIndex	(	Vector &	f_grid,
		const Index &	f_index,

	)

WORKSPACE METHOD: f_gridSelectFIndex.

Reduce f_grid to the frequency given by f_index.

This is one of the methods necessary to do line by line absorption calculations inside abs_scalar_gas_agenda.

It reduces the f_grid to only one frequency, the one given by f_index. If f_index is -1, then all frequencies are kept. This behavior is consistent with abs_scalar_gasExtractFromLookup.

	)

WORKSPACE METHOD: WriteMolTau.

Writes a 'molecular_tau_file' as required for libRadtran.

The libRadtran (www.libradtran.org) radiative transfer package is a comprehensive package for various applications, it can be used to compute radiances, irradiances, actinic fluxes, ... for the solar and the thermal spectral ranges. Absorption is usually treated using k-distributions or other parameterizations. For calculations with high spectral resolution it requires absorption coefficients from an external line-by-line model. Using this method, arts generates a file that can be used by libRadtran (option molecular_tau_file).
