This cropped south polar azimuthal equidistant planetocentric map combines data from a PJ19 RGB image, and from several methane band images. Hue and saturation are taken from the RGB image, brighntess is taken from the combined methane band image. Since methane band brightess correlates to the height of the cloud tops and hazes, bright features are reaching higher into the atmosphere. Those are especially the polar haze, and the haze above the Great Red Spot (GRS), but also some areas on smaller anticyclones, and along the turbulent zone on the latitude range of the GRS. Smaller-scale methane-bright features appear to correlate with Folded Filamentary Regions (FFRs).
