The ozone densities between 50 and 90 km are deduced from 1.27 &mgr;m airglow measured on the Solar Mesosphere Explorer satellite. The derived densities agree well with those made simultaneously from SME by the ultraviolet spectrometer. The data set extends from pole to pole at about 3 pm, for most sunlit latitudes. At low altitudes, in the mesosphere, there are larger variations in ozone density in the winter latitudes than in the summer. Above the meso-pause the day-to-day variation in ozone density is a factor of two at most latitudes and times.
