Map of the temperature deviation (in K) from the nominal thermal profile assuming a spatially uniform distribution of water, as derived from the 66.4 μm map. Jupiter is represented by the black ellipse, and its rotation axis is also displayed. The beam is represented by the gray filled circle. A relative difference of 10−15 K in the high stratospheric temperatures between the northern and southern latitudes is required to reproduce the observations. A warm south equatorial region (0−25 °S) of ~4 K higher stratospheric temperatures is identified in this map (see also Fig. 14).
