More than 130,000 emission rate profiles of the O( 1 D ) dayglow (630 nm) were observed by WINDII during 1991–1995, which provide an unprecedented resource for studying the O( 1 D ) layer, and related physics and chemistry in the thermosphere and ionosphere. This article describes the general properties of the O( 1 D ) emission layer and an empirical model derived from WINDII measurements for the O( 1 D ) emission rate as a function of the solar zenith angle and solar irradiance using the F10.7 cm flux as a proxy.
