PDF figures and text files containing the mapping contours are available in the table below
These files are meant to help users to interpret the mapping model results, create their own figures, or perform other analysis with the ionospheric mapping contours output from the model. For all files and code related to the mapping model code please visit https://github.com/marissav06/jupiter-auroral-mapping (if you are looking for the zip file containing the precalculated contour IDL .sav files needed to run the mapping program, click here.)
* The Khurana (KK2009) model uses VIP4 as the internal (planetary) field. The "KK2009 with JRM09" option uses the Khurana external field (current sheet, etc.) with JRM09 as the internal field.
Each PDF figure linked above contains 36 individual images drawn at subsolar longitudes 0º-350º in 10º increments. A sample image is shown at right.
For each model/hemisphere/mapping type, figures are available in two formats:
"Fixed": These figures are drawn fixed in System III. In the north, subsolar longitude 180 degrees points to the bottom of the page and 90 degrees points to the right. For the south, 0 degrees longitude points to the bottom of the page and 270 degrees points to the left. The local time mapping rotates with subsolar longitude.
"Rotating": These figures show what a stationary observer would see as Jupiter rotates. These figures are drawn with the subsolar longitude (roughly noon local time) pointing to the bottom of the page in the north, and to the top of the page in the south. The contours rotate as the subsolar longitude changes. For all subsolar longitudes, local times dawn and dusk correspond to the left and right side of the figure, respectively.
In all figures, each colored line maps to a constant radial distance in the magnetosphere (jovigraphic equatorial plane). Contours are drawn in 5 Rj increments, starting with 15 Rj (outer dashed black line), then in solid lines from 20 Rj (black) to 150 Rj (red). Contours are not drawn when the mapped equatorial position is beyond the Joy et al. (2002) expanded magnetopause. For model fieldline tracing, contours are drawn only out to ~60-80 Rj in some cases because the field models give erroneous results at large radial distances. Small circles on each contour indicate the rough position mapping to midnight, dawn, noon, and dusk local times. Dawn and dusk are noted in the figures. All figures for the northern hemisphere are drawn from the perspective of an observer looking down on the north pole. Southern hemisphere figures are drawn from the perspective of an observer looking up at the south pole.
Each zip file contains 36 individual text files, one for each subsolar longitude at 10 degree increments, containing the latitude and longitude coordinates of the ionospheric contours. The columns are: magnetospheric radial distance (in Rj), magnetospheric local time (in hours), mapped/traced ionospheric latitude (in degrees), and mapped/traced ionospheric longitude (in degrees, SIII lefthanded).
Example figure from one of the PDF files linked above (Vogt flux mapping approach in the northern hemisphere using the VIP4 internal field model, fixed frame). This figure was drawn for subsolar longitude = 10º.
