Departures of thermospheric [O> and [O2> from diffusive equilibrium densities are produced both by photochemical processes and by winds. Time-dependent calculations show that these departures have a diurnal average consistent with our previous steady state results. The amplitude and phase of the variations about the mean are controlled by winds. Photochemical perturbations of [O2> as a function of latitude are consistent with recent Atmosphere Explorer-C data.
