| Zusammenfassung |
| Absorption cross-section spectra for ozone and other trace gases had been
measured using the Scanning Imaging Absorption spectroMeter for Atmospheric
CHartographY (SCIAMACHY) satellite instrument at relevant atmospheric
conditions. The measured cross sections were relative cross sections and were
converted to absolute values using published data. Using SCIAMACHY's FM
cross sections as published by Bogumil et al. (2003) in the SCIAMACHY
retrievals of total ozone leads to an overestimation in the total ozone by
5% compared to collocated GOME data. This work presents the procedures
followed to correct the ozone cross-section data starting from original raw
data (optical density spectra). The quality of the revised temperature-dependent
ozone absorption cross sections is investigated over SCIAMACHY's
entire spectral range. The revised data agree well within 3% with other
published ozone cross sections and preserve the correct temperature
dependence in the Hartley, Huggins, Chappuis and Wulf bands as displayed by
the literature data. SCIAMACHY's total ozone columns retrieved using the
revised cross-section data are shown to be within 1% compared to the ozone
amounts retrieved routinely from SCIAMACHY, which uses Bogumil et al. (2003)
data but adjusted with a scaling factor of 5.3% and a wavelength shift of
0.08 nm. |
