(1)  SOUTH POLAR MAPS, 2016-2020 (PJ1-PJ26)

The following four ZIP files contain polar projection maps of Jupiter’s south polar region from JunoCam (2016-2020, PJ1-PJ26) and from amateur ground-based observers (2018 & 2020).  These maps were used in analysing the structure and dynamics of the south polar region, as reported in Rogers et al. (2022)*; the third and fourth sets are Supplementary Figures for that paper.

The JunoCam maps are in polar azimuthal equidistant projection with planetocentric latitude scale.  Maps at early perijoves were not produced as systematically as at later ones. 

One set of JunoCam maps is in colour (RGB), with the edges set at 60°S; the second set is in the 889-nm methane band (CH4), with the edges set at the equator.  The first CH4 map herein is for PJ9.  The third set consists of four TIF files which are pairs of RGB maps that can be blinked to show the wind patterns. 

The fourth set contains ground-based maps, which are in polar orthographic projection with planetographic (2018) or planetocentric (2020) latitude scale, produced using WinJUPOS The images were created by the observers as named and the maps by Andy Casely, Rob Bullen and John Rogers. They are stacked TIF’s of multiple maps, either in RGB or in near-infrared.
