Work Description

Dataset for Modeling Reconnection-driven Dynamics at Ganymede's Upstream Magnetosphere

This is the dataset for generating the figures in the paper: H.Zhou et al. "Reconnection-driven Dynamics at Ganymede's Upstream Magnetosphere: 3D Global Hall MHD and MHD-EPIC Simulations", Journal of Geophysical Research Space Physics, 2020.
All the numbering of figures are referred to the plots in the manuscript.

Magnetic Field Comparison

• Galileo_G8_flyby_MAG.dat is the ascii file for the magnetometer data during Galileo G8 flyby.
• box_Hall_B_1200.outs is the binary file for Hall MHD B field with 1s output cadence.
• box_PIC_B_1200.outs is the binary file for MHD-EPIC B field with 1s output cadence.

The processing script can be found here. Results are shown in Figure 1.

Magnetopause Contours

These requires original 3D outputs in .vtu format. The generated movies from the 20 min simulations are listed as supplements in the paper. Figure 4 are snapshots from the movie.

• t00000955_n00477070_hall.vtu is the binary file for the Hall MHD cuts in Figure 2 and 3.
• t00001050_n00509312_pic.vtu is the binary file for the PIC cuts in Figure 2 and 3.

Flux Rope

• 3d_var_region0_0_t00001205_n00037679.out is the binary file for visualizing flux rope as in Figure 5.

It can be first converted to .vtr format with the functionality provided in SWMF.jl, and then processed with any VTK compatible tools.

Static Satellite

• satellites_boundary_Hall.txt is the ascii file for storing the plasma variables for a series of static satellites along the z=0 magnetopause boundary from Hall simulation.
• satellites_boundary_PIC.txt is the ascii file for storing the plasma variables for a series of static satellites along the z=0 magnetopause boundary from MHD-EPIC simulation.
• satellites_y0_Hall.txt is the ascii file for storing the plasma variables for a series of static satellites along the y=0 magnetopause boundary from Hall simulation.
• satellites_y0_PIC.txt is the ascii file for storing the plasma variables for a series of static satellites along the y=0 magnetopause boundary from MHD-EPIC simulation.

The processing script for Figure 4 can be found here.

Diffusion Region

• 3d_var_region0_0_t00001640_n00020369.out is the binary file for Figure 7.
• 3d_var_region0_0_t00001527_n00005528.out is the binary file for Figure 8.

The processing script can be found here.

Phase Space Distribution

• cut_particles0_region0_1_t00001640_n00020369.out is the binary file for electrons for Figure 9.
• cut_particles1_region0_2_t00001640_n00020369.out is the binary file for ions for Figure 9.

The processing script can be found here.

Reconnection Rate

• CPCP_hall.txt is the processed ascii file from Hall simulation 3D outputs with ParaView and VisAna.
• CPCP_pic.txt is the processed ascii file from MHD-EPIC simulation 3D outputs with ParaView and VisAna.

The above two files are processed with this script to generate Figure 11.

Hall MHD & MHD-EPIC Comparison

A series of *.png files are attached showing the meridional and equatorial cuts of MHD quantities from the Hall MHD and MHD-EPIC results.
