abs_lookupAdapt()

void abs_lookupAdapt	(	GasAbsLookup &	abs_lookup,
		Index &	abs_lookup_is_adapted,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Vector &	f_grid,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lookupAdapt.

Adapts a gas absorption lookup table to the current calculation.

The lookup table can contain more species and more frequencies than are needed for the current calculation. This method cuts down the table in memory, so that it contains just what is needed. Also, the species in the table are brought in the same order as the species in the current calculation.

Of course, the method also performs quite a lot of checks on the table. If something is not ok, a runtime error is thrown.

The method sets a flag abs_lookup_is_adapted to indicate that the table has been checked and that it is ok. Never set this by hand, always use this method to set it!

abs_lookupCalc()

void abs_lookupCalc	(	Workspace &	ws,
		GasAbsLookup &	abs_lookup,
		Index &	abs_lookup_is_adapted,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const ArrayOfArrayOfSpeciesTag &	abs_nls,

		const Vector &	abs_t,
		const Vector &	abs_t_pert,
		const Vector &	abs_nls_pert,
		const Agenda &	abs_xsec_agenda,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lookupCalc.

Creates a gas absorption lookup table.

The lookup table stores absorption cross-sections as a function of pressure. Additionally, absorption can be stored as a function of temperature for temperature perturbations from a reference profile.

Additionally, absorption can be stored as a function of water vapor VMR perturbations from a reference profile. The variable abs_nls specifies, for which species water vapor perturbations should be generated.

Note, that the absorbing gas can be any gas, but the perturbing gas is always H2O.

		const Numeric &	h2o_step,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lookupSetup.

Set up input parameters for abs_lookupCalc.

More information can be found in the documentation for method abs_lookupSetupBatch*

Max and min values of H2O and temperature are adjusted to allow for numerical perturbations in Jacobian calculation.

The input variables abs_nls_interp_order and abs_t_interp_order are used to make sure that there are enough points in abs_nls_pert and abs_t_pert for the chosen interpolation order.

Note: For homogeneous 1D cases, it can be advantageous to calculate abs_lookup* from the 1D atmosphere, and to expand the atmosphere to 3D only after that. This particularly if nonlinear species (i.e., H2O) are involved. See also: <br> abs_lookupSetupBatch

abs_lookupSetupBatch()

void abs_lookupSetupBatch	(	Vector &	abs_p,
		Vector &	abs_t,
		Vector &	abs_t_pert,
		Matrix &	abs_vmrs,
		ArrayOfArrayOfSpeciesTag &	abs_nls,
		Vector &	abs_nls_pert,

		const Numeric &	h2o_step,
		const Vector &	extremes,
		const Index &	robust,
		const Index &	check_gridnames,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lookupSetupBatch.

Set up input parameters for abs_lookupCalc for batch calculations.

This method performs a similar task as abs_lookupSetup, with the difference that the lookup table setup is not for a single atmospheric state, but for a whole batch of them, stored in batch_atm_fields_compact*.

The method checks abs_species to decide which species require nonlinear treatment in the lookup table.

The method also checks which range of pressures, temperatures, and VMRs occurs, and sets abs_p, abs_t, abs_t_pert, and abs_vmrs accordingly.

If nonlinear species are present, abs_nls and abs_nls_pert are also generated.

Max and min values of H2O and temperature are adjusted to allow for numerical perturbations in Jacobian calculation.

The input variables abs_nls_interp_order and abs_t_interp_order are used to make sure that there are enough points in abs_nls_pert and abs_t_pert for the chosen interpolation order.

The method checks each given field using atmfields_checkedCalc. If a field does not pass the check, a run-time error is thrown. To prevent this, the parameter robust can be set to one: Invalid atmospheres are skipped, but the run continues. This matches the robust behaviour of ybatchCalc.

		const Numeric &	h2o_max,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_lookupSetupWide.

Set up input parameters for abs_lookupCalc for a wide range of atmospheric conditions.

This method can be used to set up parameters for a lookup table that really covers all reasonable atmospheric conditions.

Reference profiles of T and H2O will be constant, so that the different dimensions in the lookup table are actually "orthogonal", unlike the traditional case where we have pressure dependent reference profiles. This makes the table numerically somewhat more robust then the traditional ones, and it makes it straightforward to calculate the accuracy for the different interpolations with abs_lookupTestAccuracy.

You can give min an max values for the atmospheric conditions. The default values are chosen such that they cover the value range over the complete Chevallier91L data set, and a bit more. The statistics of the Chevallier91L data are:

min(p) / max(p) [Pa]: 1 / 104960 min(T) / max(T) [K]: 158.21 / 320.39 min(H2O) / max(H2O) [VMR]: -5.52e-07 / 0.049

WORKSPACE METHOD: abs_lookupTestAccMC.

Test accuracy of absorption lookup table with Monte Carlo Algorithm.

Explicitly compare absorption from the lookup table with line-by-line calculations for random conditions.

The quantities returned are the mean value and standard deviation of the absolute value of the relative error in percent. The relative error itself is computed for a large number of cases (pressure, temperature, and H2O VMR combinations). In the frequency dimension the maximum value is taken for each case.

Produces no workspace output, only output to the output streams.

WORKSPACE METHOD: abs_speciesAdd2.

Adds a species tag group to the list of absorption species and jacobian quantities.

The method is basically a combined call of abs_speciesAdd and jacobianAddAbsSpecies*. In this way it is not needed to specify a tag group in two different places.

Arguments exactly as for jacobianAddAbsSpecies. Note that this method only handles a single tag group, in contrast to abs_speciesAdd*.

abs_speciesSet()

void abs_speciesSet	(	ArrayOfArrayOfSpeciesTag &	abs_species,
		Index &	abs_xsec_agenda_checked,
		Index &	propmat_clearsky_agenda_checked,
		const ArrayOfString &	species,
		const Verbosity &	verbosity
	)

WORKSPACE METHOD: abs_speciesSet.

Set up a list of absorption species tag groups.

Workspace variables like abs_species contain several tag groups. Each tag group contains one or more tags. This method converts descriptions of tag groups given in the keyword to the ARTS internal representation (an ArrayOfArrayOfSpeciesTag). A tag group selects spectral features which belong to the same species.

A tag is defined in terms of the name of the species, isotopologue, and a range of frequencies. Species are named after the standard chemical names, e.g., "O3". Isotopologues are given by the last digit of the atomic weight, i.g., "O3-668" for the asymmetric ozone molecule including an oxygen 18 atom. Groups of transitions are specified by giving a lower and upper limit of a frequency range, e.g., "O3-666-500e9-501e9".

To turn on Zeeman calculation for a species, "-Z" may be appended to its name: "O2-Z" or "O2-Z-66"

To turn on line mixing calculation for a species, "-LM" may be appended to its name (or after the Zeeman tag): "O2-LM" or "O2-Z-LM-66"

The symbol "*" acts as a wild card. Furthermore, frequency range or frequency range and isotopologue may be omitted.

Finally, instead of the isotopologue the special letter "nl" may be given, e.g., "H2O-nl". This means that no absorption at all is associated with this tag. (It is not quite clear if this feature is useful for anything right now.)

Example:

<br> species = [ "O3-666-500e9-501e9, O3-686", <br> "O3", <br> "H2O-PWR98" ]

<br> The first tag group selects all O3-666 lines between 500 and <br> 501 GHz plus all O3-686 lines.

<br> The second tag group selects all remaining O3 transitions.

<br> The third tag group selects H2O, with one of the complete <br> absorption models (Rosenkranz 98). No spectrocopic line catalogue <br> data will be used for that third tag group.

<br> Note that order of tag groups in the species list matters. In our <br> example, changing the order of the first two tag group will give <br> different results: as "O3" already selects all O3 transitions, <br> no lines will remain to be selected by the <br> "O3-666-500e9-501e9, O3-686" tag.

For CIA species the tag consists of the two involved species and a dataset index. CIA species can be defined for multiple regions The dataset index determines which region to use from the corresponding CIARecord in abs_cia_data.

Example

species = [ "N2-CIA-N2-0, N2-CIA-N2-1" ]

For Hitran cross section species the tag consists of the species and the tagtype HXSEC, e.g. CFC11-HXSEC. The data for the species must be available in the hitran_xsec_data variable. abs_xsec_agenda_checked* and propmat_clearsky_agenda_checked are set to be false.

	)

Compare lookup and LBL calculation.

This is a helper function used by abs_lookupTestAccuracy. It takes local p, T, and VMR conditions, performs lookup table extraction and line by line absorption calculation, and compares the difference.

Parameters

al	Lookup table
abs_p_interp_order	Pressure interpolation order.
abs_t_interp_order	Temperature interpolation order.
abs_nls_interp_order	H2O interpolation order.
ignore_errors	If true, we ignore runtime errors in lookup table extraction. This is handy, because in some cases it is not easy to make sure that all local conditions are inside the valid range for the lookup table.
local_p
local_t
local_vmrs

Returns

The maximum of the absolute value of the relative difference between lookup and LBL, in percent. Or -1 if the case should be ignored according to the "ignore_errors" flag.

find_nonlinear_continua()

void find_nonlinear_continua	(	ArrayOfIndex &	cont,
		const ArrayOfArrayOfSpeciesTag &	abs_species,
		const Verbosity &	verbosity
	)

Find continuum species in abs_species.

Returns an index array with indexes of those species in abs_species that have continuum tags that require h2o_abs, and hence require nonlinear treatment in the absorption lookup table.

H2O itself is ignored here since that is treated separately.

We are a bit conservative here, it is possible that some of the continua do not really require H2O. Check yourself, if you want, and improve the guessing here.

Return values

cont	indices of those species with continua.

Parameters

abs_species

list of absorption species.

WORKSPACE METHOD: propmat_clearsky_fieldCalc.

Calculate (vector) gas absorption coefficients for all points in the atmosphere.

This is useful in two different contexts:

1. For testing and plotting gas absorption. (For RT calculations, gas absorption is calculated or extracted locally, therefore there is no need to calculate a global field. But this method is handy for easy plotting of absorption vs. pressure, for example.)
2. Inside the scattering region, monochromatic absorption is pre-calculated for the entire atmospheric field.

The calculation itself is performed by the propmat_clearsky_agenda*.

	)

WORKSPACE METHOD: propmat_clearskyAddFromLookup.

Extract gas absorption coefficients from lookup table.

This extracts the absorption coefficient for all species from the lookup table, and adds them to the propagation matrix. Extraction is for one specific atmospheric condition, i.e., a set of pressure, temperature, and VMR values.

Some special species are ignored, for example Zeeman species and free electrons, since their absorption properties are not simple scalars and cannot be handled by the lookup table.

The interpolation order in T and H2O is given by abs_t_interp_order and abs_nls_interp_order, respectively.

Extraction is done for the frequencies in f_grid. Frequency interpolation is controlled by abs_f_interp_order. If this is zero, then f_grid must either be the same as the internal frequency grid of the lookup table (for efficiency reasons, only the first and last element of f_grid are checked), or must have only a single element. If abs_f_interp_order is above zero, then frequency is interpolated along with the other interpolation dimensions. This is useful for calculations with Doppler shift.

For Doppler calculations, you should generate the table with a somewhat larger frequency grid than the calculation itself has, since the Doppler shift will push the frequency grid out of the table range on one side.

Some extrapolation is allowed. For pressure and frequency interpolation the standard extrapolation factor of 0.5 is applied. The factor is the default for temperature and VMR interpolation, but the extrapolation limit can here be adjusted by the extpolfac argument.
