Evolution of Titan's atmospheric temperature and composition near the poles from Cassini/CIRS

International audience We report on the monitoring of seasonal evolution near Titan's poles. Since 2010, we have observed at Titan's south pole a strong temperature decrease and the onset of a dramatic enhancement of several trace species such as complex hydrocarbons and nitriles previousl...

Description
Summary:International audience We report on the monitoring of seasonal evolution near Titan's poles. Since 2010, we have observed at Titan's south pole a strong temperature decrease and the onset of a dramatic enhancement of several trace species such as complex hydrocarbons and nitriles previously observed only at high northern latitudes (Coustenis et al. 2016, 2018 and references therein).
