Seasonal Evolution of Titan's Stratospheric Composition as a Probe of Atmospheric Dynamics at the Equator - NASA/ADS Now on home page ads icon ads Enable full ADS view NASA/ADS Seasonal Evolution of Titan's Stratospheric Composition as a Probe of Atmospheric Dynamics at the Equator Wright, Lucy ; Teanby, Nicholas ; Irwin, Patrick ; Mitchell, Dann ; Nixon, Conor ; Lombardo, Nick Abstract The equatorial region of Titan's atmosphere has intrigued astronomers ever since the Voyager spacecraft flew past Titan in the 1980s. Voyager 1 & 2 observed a sharp change in brightness at Titan's equator [1, 2], often referred to as the North-South Asymmetry (NSA). The NSA has since been observed by the Hubble Space Telescope [3-5] and in Cassini ISS images (eg, [6]). The NSA has been shown to vary seasonally [3, 7] and is attributed to the distribution of aerosols in Titan's stratosphere. There is a sharp …
