Bass-Paur vs. GOME FM • Bass Paur x-section • Proc.Quadr.Oz.Symp., p. 606,1985 • spectral resolution ~0.025 nm • spectral range 245-343 nm (SCIATRAN 245-340 nm) • 203-298 K, 5 temperatures • absolute scaling at 253.7nm using Hearn value • uncertainty 1% • GOME FM X-section • Burrows et al., JQSRT 61, 1999 • spectral resolution 0.2-0.4 nm • spectral range 231-794 nm • 202-293K, 5 temperatures • absolute scaling: chemical titration at 293 K assuming no T-dependence • uncertainty: 3-5% • source: J. Orphal, A critical review of the Absorption Cross-Sections of O3 and NO2 in the 240-790 nm Region, ESA Contract, draft version 29. March 2001. • Conclusion and recommendations: • > 340 nm GOME/SCIA FM best spectra available • 330-340 nm bias of ~1% in rel. intensity • profile retrieval up to 340 nm suffices for this study, for tropospheric studies wavelength extention needed
