“…Pressure-induced line shifts for air (δ air ) have also been included for this work. The pressure shifts from HITRAN2016 are based on multi-spectrum measurements of the ν 3 fundamental band by Benner et al [80]. These shifts depend on m (where m = N for P -and Q-branches and m = N + 1 for P -branches) and have been fit to K a dependent Figure 19: Calculated absorption cross sections at 296 K using line lists from HITRAN2016, NDSD-1000 and this work.…”

This work describes the update of NO along with the incorporation of NO 2 and N 2 O to the HITEMP database. Where appropriate, the HITRAN line lists for the same molecules have also been updated. This work brings the current number of molecules provided by HITEMP to seven. The initial line lists originating from ab initio and semi-empirical methods for each molecule have been carefully validated against available observations and, where necessary, adjustments have been made to match observations. We anticipate this work will be applied to a variety of high-temperature environments including astronomical applications, combustion monitoring, and non-local thermodynamic equilibrium conditions.

“…The study by Perrin et al [167] provided accurate line positions and absolute intensities for several NO 2 bands, including the n 2 and n 3 fundamentals and their associated hot bands. Benner et al [168] obtained precise line positions and relative intensities for the n 3 band including accurate determinations of position differences for a large number of spin-splittings. In addition, air-broadened halfwidth and air-induced pressure shift coefficients and their variations with temperature were also determined for over 1000 transitions.…”

“…In addition, air-broadened halfwidth and air-induced pressure shift coefficients and their variations with temperature were also determined for over 1000 transitions.

“…For all other transitions the values calculated using the empirical expressions of Ref. [168] were applied for the half-width, pressure shift and their temperature dependences. Values for higher K a quantum numbers were constrained to the highest measured K a (K a ¼ 9 for halfwidth and K a ¼7 for pressure-induced shift coefficients).…”

The updated 2009 edition of the spectroscopic database GEISA (Gestion et Etude des Informations Spectroscopiques Atmosphé riques; Management and Study of Atmospheric Spectroscopic Information) is described in this paper. GEISA is a computer-accessible system comprising three independent sub-databases devoted, respectively, to: line parameters, infrared and ultraviolet/visible absorption cross-sections, microphysical and optical properties of atmospheric aerosols. In this edition, 50 molecules are involved in the line parameters sub-database, including 111 isotopologues, for a total of 3,807,997 entries, in the spectral range from 10 À 6 to 35,877.031 cm À 1. The successful performances of the new generation of hyperspectral sounders depend ultimately on the accuracy to which the spectroscopic parameters of the optically active atmospheric gases are known, since they constitute an essential input to the forward radiative transfer models that are used to interpret their observations. Currently, GEISA is involved in activities related to the assessment of the capabilities of IASI (Infrared Atmospheric Sounding Interferometer; http://smsc.cnes.fr/IASI/index.htm) on board the METOP European satellite through the GEISA/IASI database derived from GEISA. Since the Metop-A (http://www.eumetsat.int) launch (19 October 2006), GEISA is the reference spectroscopic database for the validation of the level-1 IASI data. Also, GEISA is involved in planetary research, i.e., modeling of Titan's atmosphere, in the comparison with observations performed by Voyager, or by ground-based telescopes, and by the instruments on board the Cassini-Huygens mission. GEISA, continuously developed and maintained at LMD (Laboratoire de Mé té orologie Dynamique, France) since 1976, is implemented on the IPSL/CNRS (France) ''Ether'' Products and Services Centre WEB site (http://ether.ipsl.jussieu.fr), where all archived spectroscopic data can be handled through general and user friendly associated management software facilities. More than 350 researchers are registered for on line use of GEISA.

“…Therefore an update for NO 2 may have to be performed provided that these results are completed by a more extended set of broadening coefficients. Actually according to recent infrared measurements (Benner et al, 2004) the rotational dependence for these broadening coefficients is far from being negligible. Finally, for NO 2 , we used γ self = 1.42 MHz/Torr as it was calculated by Tejwani (1972).…”

In order to investigate the upper troposphere/lower stratosphere (UTLS) region of the earth's atmosphere, ESA/ESTEC (European space agency) is considering the opportunity to develop the spaceborne limb sounding millimeter sensor "MASTER" (millimeter wave acquisitions for stratosphere/troposphere exchange research). This instrument is part of the "atmospheric composition explorer for chemistry and climate interactions" (ACECHEM) project. In addition, ESA/ESTEC is developing the "MARSCHALS" (millimeter-wave airborne receiver for spectroscopic characterization of atmospheric limb sounding) airborne instrument which will demonstrate the feasibility of MASTER. The present paper describes the line-by-line database which was generated in order to meet at best the needs of the MASTER (or MARSCHALS) instrument. The linelist involves line positions, line intensities, line broadening and line shift parameters in the 294-305, 316-325, 342-348, 497-506 and 624-626 GHz spectral microwindows. This database was first generated for the target molecules for MASTER (H 2 O, O 3 , N 2 O, CO, O 2 , HNO 3 , HCl, ClO, CH 3 Cl, BrO). In addition, ten additional molecules (SO 2 , NO 2 , OCS, H 2 CO, HOCl, HCN, H 2 O 2 , COF 2 , HO 2 and HOBr) had also to be considered in the database as "possible interfering species" for the retrieval of the target molecules of MASTER. The line parameters were derived, depending on their estimated accuracy, (i) from a combination of spectral parameters included in the JPL and HITRAN catalogs (ii) from data taken into the literature or (iii) using data obtained through experimental measurements (and/or) calculations performed during the present study.
