title: Dataset of ``Plasma Distribution Solver: A Model for Field-Aligned Plasma Profiles Based on Spatial Variation of Velocity Distribution Functions"

description: This dataset contains the plasma distribution data in the Jupiter–Io system, calculated from the Plasma Distribution Solver and used for figures in the paper “Plasma Distribution Solver: A model for field-aligned plasma profiles based on spatial variation of velocity distribution functions” by K. Saito et al. (2023). The contents of files ‘all_Case_1.csv’ and ‘all_Case_2.csv’ are as follows: Position along the magnetic field line (0 at the magnetic equator) [m] (column 1) Distance from the Jovian center [km] (column 2) Magnetic latitude [rad]([degree]) (column 3(4)) Magnetic flux density [T] (column 5) The initial condition of electrostatic potential [V] (column 6) The result of electrostatic potential [V] (column 7) Number density profiles [m<sup>-3</sup>] (columns 8-17) Charge density profiles obtained from the integration of velocity distribution functions [C m<sup>-3</sup>] (column 18) Charge density profiles obtained from Poisson’s equation [C m<sup>-3</sup>] (column 19) Convergence value (column 20) Particle flux density [m<sup>-2</sup> s<sup>-1</sup>] (columns 21-30) Mean flow velocity parallel to the field line [m s<sup>-1</sup>] (columns 31-40) Plasma pressure perpendicular to the field line [Pa] (columns 41-50) Plasma pressure parallel to the field line [Pa] (columns 51-60) Plasma dynamic pressure [Pa] (columns 61-70) Perpendicular temperature [J] (columns 71-80) Parallel temperature [J] (columns 81-90) Alfvén speed considering the displacement current term in Ampère’s law [m s<sup>-1</sup>] (column 91) Alfvén speed per the speed of light (column 92) Ion inertial length using averaged mass [m] (column 93) Electron inertial length [m] (column 94) Ion Larmor radius using averaged mass [m] (column 95) Ion acoustic gyroradius using averaged mass [m] (column 96) Electron Larmor radius [m] (column 97) Current density [A m<sup>-2</sup>] (column 98) The Python codes ‘plot_all.py,’ ‘plot_plasma_beta_comparison.py,’ and ‘plot_Alfven_speed_comparison.py’ can plot Figures 5, 6, 7, and 9 of the paper using the above CSV files. The files ‘boundary_conditions_Case_1.csv’ and ‘boundary_conditions_Case_2.csv’ contain the boundary conditions for Cases 1 and 2. The zip files ‘probability_density_function_Case_1_H_Io.zip’ and ‘probability_density_function_Case_1_H_Jupiter_North.zip’ are zipped CSV files with the same name. The contents of these files are as follows: Magnetic latitude [degree] (column 1) Perpendicular velocity at the particle position [m s<sup>-1</sup>] (column 2) Parallel velocity at the particle position [m s<sup>-1</sup>] (column 3) Perpendicular velocity at the boundary [m s<sup>-1</sup>] (column 4) Parallel velocity at the boundary [m s<sup>-1</sup>] (column 5) Probability density function [s<sup>3</sup> m<sup>-3</sup>] (column 6) Differential flux per number density [cm<sup>-2</sup> s<sup>-1</sup> sr<sup>-1</sup> keV<sup>-1</sup>] (column 7) The Python code ‘plot_velocity_distribution_function.py’ can plot Figure 8 of the paper using this CSV file.
