Atomic oxygen features at 1304 and 1356 Å detected by the Orbiting Ultraviolet Spectrometer (OUVS) on Pioneer Venus are compared to theoretical emission models. Limb scans from three orbits of the OI 1304 Å emission were analyzed using an improved model which removes the restrictive assumptions of complete frequency redistribution and isothermal multiple scattering. Data‐model comparisons indicate the OI 1304 Å emission rates observed are consistent with an O density 40% of the BUS model. It is also found that the emission at 1356 Å is consistent with the sum of the CO fourth positive band at 1352 Å and the OI doublet at 1356, 1358 Å, if an O density equal to 40% of the BUS model is used to calculate the OI emission rate.
