The structure of Titan's atmosphere from Cassini radio occultations: Occultations from the Prime and Equinox missions

► Six Cassini radio occultations by Titan are presented. ► Latitudes sounded range from 79N to 75S. ► Sudden cooling is observed between 80 and 100 km in the high northern (winter) soundings. ► The northern profiles show a “flattened” tropopause region which are colder than their southern counterparts.
