The HITRAN database is a compilation of molecular spectroscopic parameters. It was established in the early 1970s and used by various computer codes to predict simulate transmission emission light gaseous media (with an emphasis on terrestrial planetary atmospheres). composed five major components: line-by-line parameters required for high-resolution radiative-transfer codes, experimental infrared absorption cross-sections (for molecules where it not yet feasible representation form),...
Abstract In recent years, extended efforts have been made to increase the potential for modeling and interpreting spectra of planetary atmospheres using HITRAN database. A significant objective is provide broadening parameters due ambient pressure He, H 2 , CO gases. Since hydrogen helium are main constituents in gas giants, carbon dioxide dominates many rocky planets, these spectroscopic data essential radiative transfer models dedicated atmospheres. HITRAN2016, He-, - -broadening their...
In this paper, we present accurate measurements of the fundamental Boltzmann constant based on a line-shape analysis acetylene spectra in ν1 + ν3 band recorded using tunable diode laser. Experimental at low pressures (0.25 − 9 Torr), have been analyzed Speed Dependent Voigt model that takes into account molecular speed dependence effects. This reproduces experimental data with good accuracy and allows us to determine precise parameters for P(25) transition band. From obtained Doppler-width...
The spectral line parameters of carbon dioxide have been measured in the laser band I (00011 ← 10001) centred at 10.4 μm. spectra were recorded room temperature using spectroscopic instrumentation far-infrared beamline, Canadian Light Source, Saskatoon, Sask. intensities, air- and self- broadened Lorentz half widths, pressure-induced shift coefficients retrieved for 48 lines a multispectrum fit technique (Benner et al.

<p>The HITRAN database is an integral component of numerous atmospheric radiative transfer models and it therefore essential that the contains most appropriate up-to-date spectroscopic parameters. To this end, HITRAN2020 scheduled to be released at end year.  The compilation edition (as tradition for database) exemplifies efficiency necessity worldwide scientific collaborations. It a titanic effort experimentalists, theoreticians scientists, who measure, calculate...
