Vertical mixing-ratio profiles of atmospheric gases can be retrieved from solar occultation spectra. The influence of systematic errors in the parameters of the models required in the analysis has been investigated. It is concluded that, because of smearing effects and other uncertainties, it may be preferable to calibrate the spectra internally by measuring absorption lines of gases such as CO2 or N2 whose vertical distributions can be assumed, rather than to rely on externally supplied information.
