Titan's stratospheric seasonal variations up to the end of the Cassini mission
International audience We have monitored the seasonal evolution near Titan's poles and equator from 2012 until the last flyby of Titan in 2017. The 2017 data we have acquired and processed here are very important as they also show that the Southern pole is finally showing a significant decrease...
