This paper describes the contents of 2016 edition HITRAN molecular spectroscopic compilation. The new replaces previous 2012 and its updates during intervening years. absorption compilation is composed five major components: traditional line-by-line parameters required for high-resolution radiative-transfer codes, infrared cross-sections molecules not yet amenable to representation in a form, collision-induced data, aerosol indices refraction, general tables such as partition sums that apply...
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. MIPAS, the Michelson Interferometer for Passive Atmospheric Sounding, is a mid-infrared emission spectrometer which part of core payload ENVISAT. It limb sounder, i.e. it scans across horizon detecting atmospheric spectral radiances are inverted to vertical temperature, trace species and cloud distributions. These data can be used scientific investigations in various research fields including dynamics chemistry altitude region between upper troposphere lower thermosphere. The...
Abstract
The products of the ClO self-reaction have been studied in a flowing chemical reactor using submillimeter wave spectroscopy. complete spectrum between 415 to 435 GHz has measured as well selected transitions range 285 GHz. major identified dimer (Cl2O2) and chlorine dioxide (OClO). observed rotational b-type spectra most abundant isotopic species35 ClOO35Cl 37ClOO35Cl analyzed. nuclear spin statistics for main species, relative abundance lesser structure determination demonstrate...
Abstract. On 13 October 2017, the Tropospheric Monitoring Instrument (TROPOMI) was launched on Copernicus Sentinel-5 Precursor satellite in a sun-synchronous orbit. One of mission's operational data products is total column concentration carbon monoxide (CO), which released to public July 2018. The current TROPOMI CO processing uses HITRAN 2008 spectroscopic with updated water vapor spectroscopy and produces product compliant mission requirement 10 % precision 15 accuracy for single...
The balloon-borne instrument TELIS (TErahertz and submillimetre LImb Sounder) is a three-channel superconducting heterodyne spectrometer for atmospheric research use. It detects spectral emission lines of stratospheric trace gases that have their rotational transitions at THz frequencies. One the channels based on integrated receiver (SIR) technology. We demonstrate first time capabilities SIR technology spectroscopy in general, limb sounding particular. also show application not limited to...
High‐resolution Fourier transform infrared measurements of the three ozone fundamentals have been performed. A total 16 spectra recorded, including pure as well oxygen‐ and nitrogen‐broadened at room temperature 200 K. Focus was set on quality assurance for sample preparation prevention instrumental retrieval errors. Line positions, line strengths pressure‐broadened half widths determined. quantum mechanical analysis positions performed, improved molecular constants were obtained. Individual...
Abstract. This paper gives an overview of the MIPAS Level 1B (L1B) processor whose main objective is to calibrate atmospheric measurements radiometrically, spectrally and geo-located. It presents also results instrument characterization done on ground during first years in-flight. An accurate calibration mandatory for high quality retrievals. has shown very good performance stability. The noise equivalent spectral radiance ranges from 3 50 nW/(cm2 sr cm−1) well within requirements over...
Ab initio calculations of water intensities are becoming mature and claimed to have 1% accuracy in many cases. Experimental with can be achieved some care. An intercomparison ab against experimental is presented for a variety infrared bands H216O H218O H217O. A new calculated line list which uncertainties the evaluated. Much data show agreement within 2% between experiment, however, bands, notably those involving excitation stretching modes, there larger offsets up 8% attributed calculation...
Nonintrusive systems for the measurement on test rigs of aeroengine exhaust emissions required engine certification (CO, NOx, total unburned hydrocarbon, and smoke), together with CO2 temperature have been developed. These results compared current certified intrusive measurements an test. A spectroscopic database data-analysis software has developed to enable Fourier-transform Infrared concentrations molecular species. CO2, CO, NO data showed agreement techniques approximately ±30%....
