[21.02] Disk resolved UV-Vis-NIR observations of Titan's aerosols

Four instruments on the Hubble Space Telescope were used to observe Titan shortly after its southern summer solstice in 2002. The data set includes disk-resolved polarimetry from 0.2-2 microns, which shows limb polarization characteristic of small particles. Spectroscopy and imaging data show the north-south asymmetry has reversed since the 1990s and show a pronounced south polar hood. Current work is focused on testing hypotheses regarding the size and shape of the aerosols and regarding the seasonal variations in the aerosol distribution. A preliminary report on the new results will be presented.

Based on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555. These observations are associated with program #9385.
