The structure of Titan's atmosphere from Cassini radio occultations

► Four Cassini radio occultations by Titan are presented. ► Latitudes sounded are 31-34°S and 53°S. ► Surface temperature is 93 K at 31-34°S and 1 K colder at 53°S. ► Tropopause temperature is 70 K at 31-34°S and 1 K colder at 53°S. ► Dawn profiles temperatures lie along a dry adiabat for most of the lowest 2 km.
