Multispectrum fit of non-Voigt lineshape in the H2O v2 band
No full textA new fitting tool for analysis of multiple molecular absorption spectra utilizing a microwindow-based line-by-lineapproach
has been developed. Its capabilities include the choice of numerous different line shape models, from a simple
Voigt to more sophisticated models like a speed-dependent Galatry including line-mixing. A comfortable manual mode as
well as a fully automatic mode have been implemented including various quality assessment procedures like the
monitoring of correlation coefficients or the supply of useful information e.g. needed for file cuts (single spectrum
residuals). As a first application the new tool is used to re-analyze water vapor absorption spectra in the 1250-1750 cm range. The measurements include pure water as well as water/air-mixture measurements and cover a wide range of column densities. The total air pressure and partial pressure ranges were 50-1000 mb and 0.001-5 mb, respectively.
Whereas the original analysis was based on single spectrum fits applying the Voigt procedure, in the present
multispectrum fit the speed-dependent Voigt lineshape was used. The advantages of a multispectral analyis approach as
well as the need for consideration of narrowing effects is illustrated by the presentation of differences in residuals as well as resulting line parameters for selected transitions. As indicated in opaque as well as non opaque lines could be fitted
with the speed-dependent Voigt while the pure Voigt yields to narrow opaque lines

A rapid retrieval methodology based on the spectrally integrated Voigt function for space observation spectral radiance data
No full textIn our recent publication, we proposed the application of the spectrally integrated Voigt function (SIVF) to a line-by-line (LBL) radiative transfer modelling1. We applied the GENSPECT LBL radiative transfer model that utilizes the HITRAN database to generate synthetic spectral data due to thermal or solar radiation of the Earth or planetary atmosphere2. It has been shown that the SIVF methodology enables the computation of a LBL radiative transfer at reduced spectral resolution model without loss in accuracy. In contrast to the traditional method of computation, the SIVF implementation accounts for the area under the Voigt function between adjacent grid points resulting in well-preserved shape of a spectral radiance even at low spectral resolution. This significant advantage of the SIVF methodology can be applied in the rapid retrieval of the space observation data, required for real-time control and decision making in future generation of the Argus3 remote-sensing microspectrometers. The spectrally integrated methodology can be generalized to other linebroadening profiles, such as Galatry, Rautian-Sobelman or speed dependent profiles, to prevent underestimation of the spectral radiance that always occurs at reduced spectral resolution1 in any LBL radiative transfer model using a traditional method of computation.Session III: Line Shapes.

ANALYSIS OF SPECTRA III. VOIGT SHAPED LINES

Gomez, JQSRT, 18, 555 (1977).Author Institution:Pressure broadening of spectral lines can cause fine details in the absorption spectra of gases to be lost. As the pressure is decreased the details are observed but the line shape typically changes from a Lorentz shape to the Voigt shape. It is shown that, provided the physical conditions of the sample are known, the line intensity, position and Lorentz width can be determined by spectral curve fitting for a wide variety at Voigt shaped lines. The technique of Pierluissi et al. (1) was used to calculate the absorption coefficients of the lines
