Near‐infrared absorption cross sections and integrated absorption intensities of molecular oxygen (O₂, O₂‐O₂, and O₂‐N₂)

Abstract

Abstract. Near-infrared absorption cross sections and integrated absorption intensities of gas phase oxygen and nitrogen mixtures have been determined from laboratory measurements using a coolable multipass gas cell and Fourier transform spectroscopy. Spectra were re-

“…The spectral line parameters are based on the HITRAN linelist (Rothman et al, 2005), with improvements to the O 2 7882 cm −1 band (Newman et al, 2000;Yang et al, 2005), CO 2 6228 cm −1 and 6348 cm −1 bands (Toth et al, 2006(Toth et al, , 2007, the CH 4 6002 cm −1 band (Frankenberg et al, 2008) (Smith and Newnham, 2000;Smith et al, 2001) is also included to improve estimation of the continuum in the O 2 7882 cm −1 band. The modified linelist is available upon request to Geoff Toon (JPL).…”

“…[55], and modified in accordance with Yang et al [56]. Collision-induced O 2 absorption is present in this band and is fitted using a line list based on laboratory measurements by Smith & Newnham [57] to minimize its impact on the discrete lines. Quadrupole O 2 lines have been added based on Gordon et al [41].…”
