The role of nonthermal oxygen atoms in the vertical distribution of the O I 989 Å EUV multiplet intensity is investigated using a thermospheric radiative transfer code. The superthermal oxygen concentration and temperatures are derived from the energy distribution functions of the O( 3 P ) atoms calculated by a Monte Carlo stochastic model, and their effect on UV radiative transfer is compared to sounding rocket observations. The calculated intensity increase associated with the perturbation of the Doppler profile by the presence of hot O( 3 P ) atoms is shown to be insufficient to account for the set of sounding rocket EUV intensity data.
