“…The Rayleigh optical depth is computed for a standard mid latitude atmosphere winter or summer (McClatchey et al, 1972), at the altitude of Briançon. The ozone optical depth uses the Paur and Bass (1985) ozone cross sections and the ozone total column amount given by the Total Ozone Mapping Spectrometer (TOMS) (McPeters et al, 1998), for Briançon. The AOD is therefore retrieved as…”

“…He found that three sets of ozone CS have an overall agreement of 1-2% after accounting for wavelength shifts, baseline effects, and spectral resolution. These include: (1) Bass-Paur CS (Bass and Paur, 1985;Paur and Bass, 1985) (abbreviated as BP), (2) Brion CS (Daumont et al, 1992;Brion et al, 1993;Malicet et al, 1995) (abbreviated as BDM), and (3) GOME flight model CS ) (abbreviated as GMFM). The BP and BDM CS are especially close, within 1% (Orphal, 2002).…”

Impact of using different ozone cross sections on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements

Abstract.We investigate the effect of using three different cross section data sets on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements (289-307 nm, 326-337 nm). These include Bass-Paur, Brion, and GOME flight model cross sections (references below). Using different cross sections can significantly affect the retrievals, by up to 12 Dobson Units (DU, 1 DU=2.69×10 16 molecules cm −2 ) in total column ozone, up to 10 DU in tropospheric column ozone, and up to 100% in retrieved ozone values for individual atmospheric layers. Compared to using the Bass-Paur and GOME flight model cross sections, using the Brion cross sections not only reduces fitting residuals by 15-60% in the Huggins bands, but also improves retrievals, especially in the troposphere, as seen from validation against ozonesonde measurements. Therefore, we recommend using the Brion cross section for ozone profile retrievals from ultraviolet measurements. The total column ozone retrieved using the GOME flight model cross sections is systematically lower, by 7-10 DU, than that retrieved using the Brion and Bass-Paur cross sections and is also systematically lower than Total Ozone Mapping Spectrometer (TOMS) observations. This study demonstrates the need for improved ozone cross section measurements in the ultraviolet to improve profile retrievals of this key atmospheric constituent.

“…Comparison of the observed spectrum with one measured in the laboratory allows the determination of total column ozone in the atmosphere. The results reported in this work are referenced to the laboratory ozone absorption coefficient measurements of Bass and Paur (1985) and Paur and Bass (1985). Moonlight is directed into the Brewer instrument by the same pointing optics used standard deviation of the individual observations about the mean is taken as an estimate of the precision of the measurement.…”
