Limiting profiles for the equatorial thermal structure of Titan in the 0-200 km altitude range are presently obtained by reanalyzing Voyager 1 radio-occultation refractivity profiles, taking mean molecular weight uncertainties into account. Spectra calculated from the IR thermal profiles in the CH{sub 4} nu(4) band at 7.7 microns are compared with Voyager IRIS observations in order to constrain both the abundances of major atmospheric components and the stratospheric temperatures. A nominal temperature and composition profile of Titan's atmosphere is given in the form of tabulated values between ground level and 200 km. 44 refs.
