Cassini UVIS observations of Titan ultraviolet airglow intensity dependence with solar zenith angle
West, R. A.; Esposito, L. W.; Royer, E. M. +3 more
The Cassini Ultraviolet Imaging Spectrometer (UVIS) observed the airglow (dayglow and nightglow) of Titan over a range of solar zenith angles (SZA) from 14 to 150° on five separate observations obtained between 2008 and 2012. The modeling of the solar cycle normalized UVIS observations indicates that a Chapman layer function provides a satisfactor…
