Retrieved temperatures in the upper troposphere and stratosphere from the entire Cassini mission. Temperatures are displayed at five pressure levels: a 0.5 mbar, b 1.1 mbar, c 2.5 mbar, d 5.0 mbar, and e 110 mbar. Colours refer to dates given by the legend. Saturn’s equatorial oscillation is observed at low latitudes58, the effects of the Great Northern Storm are visible at northern mid-latitudes61 and the reversal of the stratospheric temperature asymmetry is most evident at the poles (this work)
