HITEMP, the high-temperature molecular spectroscopic database

TLDR
In this paper, a new molecular spectroscopic database for high-temperature modeling of the spectra of molecules in the gas phase is described, called HITEMP, which is analogous to the HITRAN database but encompasses many more bands and transitions than HitRAN for the absorbers H2O, CO2, CO, NO and OH.
Abstract
A new molecular spectroscopic database for high-temperature modeling of the spectra of molecules in the gas phase is described. This database, called HITEMP, is analogous to the HITRAN database but encompasses many more bands and transitions than HITRAN for the absorbers H2O, CO2, CO, NO, and OH. HITEMP provides users with a powerful tool for a great many applications: astrophysics, planetary and stellar atmospheres, industrial processes, surveillance, non-local thermodynamic equilibrium problems, and investigating molecular interactions, to name a few. The sources and implementation of the spectroscopic parameters incorporated into HITEMP are discussed.

A detailed modeling study of radiative heat transfer in a heavy-duty diesel engine

TL;DR: In this paper, an in-depth investigation of radiative heat transfer is performed for a heavy-duty diesel truck engine over a range of operating conditions, and results from 10 different combinations of turbulent combustion models, spectral radiation property models, and RTE solvers are compared to provide insight into the global influences of radiation on energy redistribution in the combustion chamber, heat losses, and engine-out pollutant emissions (NO and soot).

On the Cool Side: Modeling the Atmospheres of Brown Dwarfs and Giant Planets

TL;DR: In this paper, the authors describe the process of incorporating these complexities into one-dimensional radiative-convective equilibrium models of sub-stellar objects and discuss the underlying mathematics as well as the techniques used to model the physics, chemistry, radiative transfer, and other processes relevant to understanding these atmospheres.

Efficient full-spectrum correlated-k-distribution look-up table

TL;DR: Results show that the new table gives results of similar accuracy but at considerably cheaper computational cost than the previous table for both gas mixtures and gas-soot mixtures.

The HITRAN 2008 molecular spectroscopic database

TL;DR: The new HITRAN is greatly extended in terms of accuracy, spectral coverage, additional absorption phenomena, added line-shape formalisms, and validity, and molecules, isotopologues, and perturbing gases have been added that address the issues of atmospheres beyond the Earth.

The hitran molecular database: editions of 1991 and 1992

TL;DR: The HITRAN molecular absorption database as mentioned in this paper contains line parameters for 31 species and their isotopomers that are significant for terrestrial atmospheric studies, including chlorofluorocarbons and other molecular species that are not amenable to line-by-line representation.

The determination of an accurate isotope dependent potential energy surface for water from extensive ab initio calculations and experimental data

TL;DR: In this article, a high quality ab initio potential energy surface (PES) and dipole moment function (DPM) for water has been determined and an adjusted PES is empirically adjusted to improve the agreement between the computed line positions and those from the HITRAN 92 data base with J⩽5 for H216O.

A high-accuracy computed water line list

TL;DR: The most complete water line list in existence, comprising over 500 million transitions (65 per cent more than any other list) and also the most accurate (over 90 per cent of all known experimental energy levels are within 0.3 cm −1 of the BT2 values) is presented in this article.
