(a) Visible image of Jupiter's Little Red Spot, taken by the New Horizons spacecraft. Temperature maps on constant pressure surfaces at 400 mbar (b), 300 mbar (c), and 200 mbar (d) from inversion of images of Jupiter's thermal radiances taken through approximately 1 µm-wide filters centered at 13.04, 17.65, 18.72, and 19.50 µm, which are primarily sensitive to temperatures in the 200-400 mbar pressure range. The spatial resolution is equivalent to 1.5 degrees in longitude and 1.8 degrees in latitude. The LRS and small oval are cold anticyclones, as is the south tropical disturbance nearby. A warm, cyclonic region is seen south of the LRS.
