Detailed Description

User interface for dealing with pure line mixing calculations.

Note: If defined using parameterized form, the normal line-functions approach is faster and more appropriate. These functions should first compute the relaxation, not simply use the relaxation

Function Documentation

◆ abs_hitran_relmat_dataReadHitranRelmatDataAndLines()

void abs_hitran_relmat_dataReadHitranRelmatDataAndLines ( HitranRelaxationMatrixData abs_hitran_relmat_data,
ArrayOfArrayOfAbsorptionLines abs_lines_per_species,
const ArrayOfArrayOfSpeciesTag abs_species,
const String basedir,
const Numeric linemixinglimit,
const Numeric fmin,
const Numeric fmax,
const Numeric stot,
const String mode,
const Verbosity verbosity 
)

WORKSPACE METHOD: abs_hitran_relmat_dataReadHitranRelmatDataAndLines.

Reads HITRAN line mixing data from a basedir The basedir must point at line mixing data as provided by HITRAN. The lines will be changed such that ALL CO2 lines are truncated before adding the HITRAN line mixing lines.

The available modes are such that "VP*" uses Voigt profiles and "SDVP*" uses speed-dependent Voigt profiles, where the "_Y" signifies if Rosenkranz-style line mixing is considered or not, and the "W" at the end signifies that full calculations are used. At the line mixing limit, line mixing is simply turned off.

The "FullW" mode uses Lorentzian calculations with the full relaxation matrix until the line mixing limit is reached and it switches to Voigt.

The HITRAN LM data is available for download at: https://hitran.org/supplementary/
