Saturn Stratospheric Hazes from Cassini Limb Images

Tuesday, June 21 2011 - 5:13 pm, PDT
We will analyze Cassini data to produce detailed haze extinction profiles for both northern and southern latitudes on Saturn down to pressure levels ~50 mbar, with methods similar to those used by Rages et al. (1999) on Galileo images of Jupiter, and with the expectation of similar results. We will perform a similar analysis of archival Voyager data to explore Saturn's southern mid-latitudes almost one saturnian year earlier. We will use this information to determine the fractal scattering properties of the stratospheric hazes, and in combination with a microphysics model including fractal aggregate hazes, to determine how and where these hazes are being produced, transported, and destroyed.
