Spatial and temporal variations in Titan's surface temperatures from Cassini CIRS observations

► Modeling of Cassini CIRS far infrared data for Titan surface temperature spatial and temporal retrievals. ► Detection of latitudinal variations of the surface temperature: asymmetric decrease towards the poles due to different seasons in the two Titan hemispheres. ► Surface temperature seasonal variations up to 2 K observed at 60°N from winter to early northern spring. ► First detection of diurnal changes in the surface temperature around the equatorial regions of about 1.5 K.
