Vacuum-ultraviolet radiation measurements have been shown to provide information about the concentration of atomic species in hypersonic flows. Broad band data was obtained for radiation from the atomic O system at 130.4 nm and a model was successfully proposed. Instrumentation with better spectral resolution can be flown on future spacecraft flying at higher altitudes and faster speeds. This paper considers extensions to the O VUV radiation model and a new model for atomic N VUV radiation as well. The models are applied to the conditions for future flights at approximately 8 km/sec between the altitudes of 100 to 160 km.
