Maps of Jupiter’s south polar region (JunoCam and ground-based)
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 a paper submitted for publication (2021 March): ‘Flow patterns of Jupiter’s south polar region’, by J.H. Rogers et al. Full details are in the paper*.
The JunoCam maps are in polar azimuthal equidistant projection with planetocentric latitude scale. The images were created by the JunoCam team and the maps by Gerald Eichstädt and John Rogers. At every perijove, Gerald produces polar projection maps of all the individual images and John assembles these into composite maps. Maps at early perijoves were not produced as systematically as at later ones, and the first CH4 map herein is for PJ9.
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 third set consists of four TIF files which are pairs of RGB maps that can be blinked to show the wind patterns. These are Supplementary Figures for the paper: Suppl.Figs. S1b (PJ15), S2b (PJ16), S3b (PJ17), & S4b (PJ21).
The ground-based maps 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-IR.
