AB: WINDII data provide the first comprehensive observations of the O($^1$D) emission rate (the red line) at altitudes of 100-280 km in both latitude and local time domains. Data from three December solstice seasons (1991/92, 1992/93, and 1994/95) show that the O($^1$D) airglow emission rate strongly depends on the solar radiation as a function of the solar zenith angle, which is related to the local time and latitudinal variations, and a function of the F10.7cm solar flux, which is related to the solar cycle. Dynamic effect, including tides and planetary waves, on the airglow emission rate is also observed. WINDII O($^1$D) data are compared to simulations by the airglow model, GLOW, showing satisfactory agreement. The simulations can be improved by using measured plasma data instead of the IRI model data.
