MHD-AEPIC simulation for bursty bulk flows
Creator: Xiantong Wang, xtwang@umich.edu, 01/31/2024
This data set contains the simulation results that are used to produce the figures in the manuscript: Xiantong Wang et al. "Electron energization with bursty bulk flows: MHD (MagnetoHydroDynamics) with Adaptively Embedded Particle-in-Cell (MHD-AEPIC) Simulation".
MHD-AEPIC is a physical based model that is capable of conducting multi-scale global Earth's magnetosphere simulation.
The detailed description of the MHD-AEPIC model can be found in the paper:
Wang, X., Chen, Y., & Tóth, G. (2022). Global magnetohydrodynamic magnetosphere simulation with an adaptively embedded particle-in-cell model. Journal of Geophysical Research: Space Physics, 127, e2021JA030091. https://doi.org/10.1029/2021JA030091.
The .plt file is the binary file for Tecplot software and the .lay file is the plotting script opened by Tecplot to generate figures, respectively.
The .dat and .sat file ares ascii files that can be read by most major programming languages. In this work, they are visualized using Python scripts.
The .ipynb files can be opened by Jupyter notebook software.
The code generating the simulation data is the Space Weather Modeling Framework(SWMF) https://github.com/SWMFsoftware/SWMF developed in the University of Michigan, the SWMF is a combination of multiple components, the code versions (date and commmit hash #) of each components are listed below:

Figure 1
This Panel (a) is generated by Tecplot. The data file is 3d__var_4_t20170516133000_n00316753.plt and the Tecplot layout file is overlook.lay.
Panel (b) is plotted by Python script in plot_satellite.ipynb, the data source files are mms1_obs_field.dat, mms1_obs_velocity.dat and sat_mms1_traj_re.sat. Panel (c) is plotted by Python script in plot_solarwind.ipynb , the data source files are IMF_20170516.dat and AE_obs.dat.
Figure 2
This figure is the comparison between the model outputs and observations. The plot is generated by the Jupyter Notebook plot_pyspedas.ipynb.
Notice that in this jupyter notebook, a python package pyspedas was imported and the satellite observational data will be downloaded automatically.
Figure 3
This figure is the illustration of the evolution of the global structure of the BBF, and the associated electron velocity distribution functions.
Panels (a)-(d) are generated by Tecplot. The layout files and corresponding data files are listed below:
| Time | Layout file | Data files |
|---|---|---|

The particle data is saved in 3 zip files started with 3d_particle_region0, and the plotting script is in plot_vdf_electron_paper.ipynb.
Figure 4
This figure demonstrates the electron pitch angle distributions associated with BBF. Panels (a1)-(a3) and (b1)-(b2) are plotted with the particle data in Figure 3 (3 zip files started with 3d_particle_region0), and the plotting script is in pitch_angle_paper_1351.ipynb. Panel (c) is plotted by plot_fpr.ipynb. The associated data files are line_1349.dat, line_1350_1.dat and line_1351.dat.
