Line-of-sight Doppler winds in Saturn’s stratosphere retrieved around 0.5–1 mbar on January 14 and 22, 2012, from the ALMA CO (J=2–1) mapping observations. The eastern and western limb velocities (left axis) are plotted as a function of latitude in red and blue, respectively, with 1-σ error bars. The region obscured by the rings and from which we do not retrieve wind speeds is masked by a light yellow box. The black line shows the variation of the latitudinal resolution as a function of latitude (right axis). CML stands for Central Meridian Longitude, and SIII stands for System III. Note the symmetry between the east and west limb wind speeds, demonstrating the robustness of our measurements up to 80°N.
