Abstrakt: A method is presented for retrieving pressure, temperature, and ozone mixing ratio profiles from multilevel high resolution earthlimb emission data taken in the spectral region near the CO_2Q-branch at 791.5 cm^−1. Theory is developed for the construction of a retrieval algorithm which brings the magnitudes of calculated and measured CO_2 and O_3 features into agreement by adjusting a hydrostatic trial atmosphere having one fixed reference pressure. It is shown that overlap between the CO_2 and O_3 features can be used to determine the correct reference pressure. The method is examined using simulations to demonstrate the retrieval of vertical profiles of pressure, temperature, and ozone mixing ratio in the stratosphere. Numerical studies of the effects of uncertainties in line parameters and instrument calibration errors are also presented.
