Simultaneous measurements of stratospheric HOx, NOx, and Clx: Comparison with a photochemical model

“…The AT-MOS measurements were obtained at slightly lower latitudes (¥ 28 ) than our measurements (32 -37 N), which could explain some of the discrepancy. The fact that different vibrational bands are used by FIRS-2 and ATMOS retrievals is unlikely to cause the discrepancy, since all previous balloon measurements, including BLISS, use the same vibrational bands for retrieval as ATMOS, and the uncertainties in band strengths are about 10% [Goldman et al, 1975;Giver et al 1984;May et al, 1987]. Figure 3b compares measured and modeled profiles for HNO 3 .…”

MIPAS database: new HNO<sub>3</sub> line parameters at 7.6 µm validated with MIPAS satellite measurements

“…Figure 7 compares the PNNL experimental absorption cross sections at 7.6 µm with absorption cross sections calculated at the same conditions using MIPAS-2015 and MIPAS-OLD (assuming that the N 2 -broadening coefficients are the same as the air-broadening coefficients provided in these databases). Figure 7 shows that the agreement is significantly Giver et al (1984) 2.57 (13) 5.15 (16) 2.00 (16) Massie et al (1985) 1.98 (30) 3.72 (56) 1.88 (57) Hjorth et al (1987) 2 All the intensities are given in 10 −17 cm −1 (molecule cm 2 ) −1 at T = 296 K, 7.6 µm/11 µm R= 7.6 µm S band (296 K)/ 11 µm S band (296 K). 1 PNNL: Pacific Northwest National Laboratory.…”

“…Possible explanations of these rather large standard deviations include the fact that it is not always possible to avoid blended lines in the congested 7.6 µm spectral region, even if care was taken to avoid them, and that the theoretical model used to compute the line intensities is still imperfect, as discussed in detail in Perrin (2013). Flaud et al (2006) reviewed the integrated band intensities reported in the literature at 11 and 7.6 µm (Goldman et al, 1971;Giver et al, 1984;Massie et al, 1985;Hjorth et al, 1987;Chackerian et al, 2003). As shown in Table 5, these literature results are in reasonable agreement with each other.…”

1995 Atmospheric Trace Molecule Spectroscopy (ATMOS) linelist

“…and CFC-11 1bottom2 in ATMOS data by the use of laboratory cross sections. 14 The intensities of the n 5 and 2n 9 near 900 cm 21 and n 4 and n 3 near 1300 cm 21 were renormalized by the use of Goldman et al 57 and Giver et al, 58 unpublished laboratory data and ATMOS atmospheric data. There are considerable differences in absolute intensity studies; for the interim, it is thought that the normalization selected here sets the relative band intensities to within 610%, but the absolute uncertainties for the integrated band intensities may be 10% to 15%.…”
