During the Huygens probe mission at Titan on 14th January 2005, the Huygens Atmospheric Structure Instrument (HASI) obtained measurements of atmospheric properties from up above 1400 km down to the ground, thus inferring the atmospheric structure. The atmospheric profile along the Huygens probe trajectory during entry phase have been retrieved from the accelerometers data, while below 160 km direct pressure and temperature measurements have been performed. The vertical temperature profile retrieved from HASI data is in very good agreement with the model derived from Voyager's observations, confirms the evidence for a stratopause and the inversion layers in the upper atmosphere as observed during stellar occultations and yielded new details on atmospheric structure.
