		ArrayOfVector &	abs_cont_parameters,
		const String &	tagname,
		const String &	model,
		const Vector &	userparam,
		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.

[out]	abs_cont_models	WS Output

◆ abs_cont_descriptionInit()

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.

Author: Thomas Kuhn; Stefan Buehler

Parameters

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

◆ abs_h2oSet()

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

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.

void abs_lines_per_speciesAddMirrorLines	(	ArrayOfArrayOfLineRecord &	abs_lines_per_species,
		const Numeric &	max_f,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lines_per_speciesAddMirrorLines.

Adds mirror lines at negative frequencies to abs_lines_per_species.

For each line at frequency +f in abs_lines_per_species a corresponding entry at frequency -f is added to abs_lines_per_species. The mirror lines are appended to the line list after the original lines.

		const Vector &	f_grid,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lines_per_speciesCompact.

Removes all lines outside the defined lineshape cutoff frequencies from abs_lines_per_species. This can save computation time. It should be particularly useful to call this method after abs_lines_per_speciesAddMirrorLines*.

Author: Axel von Engeln; Stefan Buehler

		const ArrayOfLineRecord &	abs_lines,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Verbosity &	verbosity
	)

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 isotopologues than the main isotopologue).

◆ abs_lines_per_speciesReadFromCatalogues()

void abs_lines_per_speciesReadFromCatalogues	(	ArrayOfArrayOfLineRecord &	abs_lines_per_species,
		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.

◆ abs_linesArtscat4FromArtscat3()

void abs_linesArtscat4FromArtscat3	(	ArrayOfLineRecord &	abs_lines,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_linesArtscat4FromArtscat3.

Convert a line list from ARTSCAT-3 to ARTSCAT-4 format.

ARTSCAT-4 lines contain more information than ARTSCAT-3 lines, particularly they contain separate broadening parameters for six different broadening species. So a real conversion is not possible. What this method does is copy the air broadening (and shift) parameters from ARTSCAT-3 to all ARTSCAT-4 broadening species. The case that one of the broadening species is identical to the Self species is also handled correctly.

The idea is that the ARTSCAT-4 line list generated in this way should give identical RT simulation results as the original ARTSCAT-3 list. This is verified in one of the test controlfiles.

Currently only broadening and shift parameters are handled here. There are some other additional fields in ARTSCAT-4, which we so far ignore.

		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const ArrayOfString &	shape,
		const ArrayOfString &	normalizationfactor,
		const Vector &	cutoff,
		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.

For detailed documentation on the available options for the input parameters see documentation of method abs_lineshapeDefine.

void abs_lineshapeDefine	(	ArrayOfLineshapeSpec &	abs_lineshape,
		const String &	shape,
		const String &	forefactor,
		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 Faddeeva_Algorithm_916: Faddeeva function based on Zaghloul, M.R. and A.N. Ali (2011). Implementation by Steven G. Johnson under the MIT License (attainable through http://ab-initio.mit.edu/Faddeeva)

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

		const Numeric &	fmax,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_linesReadFromHitran.

Read all the lines from HITRAN 2004 and later catalogue file in the given frequency range. Otherwise a runtime error is thrown.

Records of molecules unknown to ARTS are ignored but a warning is issued. In particular this happens for CH3OH (HITRAN molecule number 39) because there is no total internal partition sum available.

The database must be sorted by increasing frequency!

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 propmat_clearsky_agenda*. What the method does is to prepare absorption input parameters (pressure, temperature, VMRs), from the input parameters to propmat_clearsky_agenda.

		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Vector &	rtp_vmr,
		const Vector &	rtp_los,
		const Vector &	rtp_mag,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: propmat_clearskyAddFaraday.

Calculates absorption matrix describing Faraday rotation.

Faraday rotation is a change of polarization state of an electromagnetic wave propagating through charged matter by interaction with a magnetic field. Hence, this method requires abs_species* to contain 'free_electrons' and electron content field (as part of vmr_field) as well as magnetic field (mag_u_field, mag_v_field*, mag_w_field) to be specified.

Faraday rotation affects Stokes parameters 2 and 3 (but not intensity!). Therefore, this method requires stokes_dim>2.

Like all 'propmat_clearskyAdd*' methods, the method is additive, i.e., does not overwrite the propagation matrix propmat_clearsky, but adds further contributions.

WORKSPACE METHOD: propmat_clearskyAddFromAbsCoefPerSpecies.

Copy propmat_clearsky from abs_coef_per_species. This is handy for putting an explicit line-by-line calculation into the propmat_clearsky_agenda*. This method is also used internally by. propmat_clearskyAddOnTheFly*. Like all other propmat_clearsky methods, this method does not overwrite prior content of propmat_clearsky, but adds to it.

WORKSPACE METHOD: propmat_clearskyAddOnTheFly.

Calculates gas absorption coefficients line-by-line.

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

1. AbsInputFromRteScalars 2. Execute abs_xsec_agenda 3. abs_coefCalcFromXsec 4. propmat_clearskyAddFromAbsCoefPerSpecies

The calculation is for one specific atmospheric condition, i.e., a set of pressure, temperature, and VMR values.

		const Verbosity &	verbosity
	)

WORKSPACE METHOD: propmat_clearskyAddParticles.

Calculates absorption coefficients of particles to be used in clearsky (non-cloudbox) calculations.

This is a method to include particles (neglecting possible scattering components) in a clearsky calculation, i.e. without applying the cloudbox and scattering solvers. Particles are handled as absorbing species with one instance of 'particles' per particle type considered added to abs_species. Particle absorption cross- sections at current atmospheric conditions are extracted from the single scattering data stored in scat_data_array, i.e., one array element per 'particles' instance in abs_species is required. Number densities are stored in vmr_field_raw or vmr_field as for all abs_species*, but can be taken from (raw) pnd_field type data.

A line-of-sight direction rtp_los is required as particles can exhibit directional dependent absorption properties, which is taken into account by this method. ParticleType2abs_speciesAdd* can be used to add all required settings/data for a single particle type at once, i.e. a 'particles' tag to abs_species, a set of single scattering data to scat_data_array* and a number density field to vmr_field_raw (vmr_field is derived applying AtmFieldsCalc once VMRs for all abs_species* have been added).

Like all 'propmat_clearskyAdd*' methods, the method is additive, i.e., does not overwrite the propagation matrix propmat_clearsky, but adds further contributions.

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).
