MHD model output for Ganymede's magnetosphere during Juno's flyby

<p>This dataset contains the complete simulation output from&nbsp;our MHD model of&nbsp;Ganymede&#39;s magnetosphere adapted to Juno&#39;s PJ34 flyby in 2021 (Duling et al. 2022).</p> <p>The data was obtained by our application of the PLUTO simulation code v4.4 (Mignone et al. 2007) (http://plutocode.ph.unito.it/) described in Duling et al. 2022.</p> <p>The dataset includes the simulation variables on the simulation grid for a single timestep after steady state was reached. The grid has spherical geometry (r, theta, phi) with phi=0&deg; longitude pointing towards Jupiter (positive y axis of the GPhiO system), phi=90&deg; longitude pointing in the upstream direction (negative x axis of GPhiO) and theta=0&deg; latitude at Ganymede&#39;s north pole (positive z axis of GPhiO). The following model variables are included:</p> <p>rho: plasma mass density<br> prs: thermal plasma pressure<br> vx1: plasma velocity radial&nbsp;component<br> vx2: plasma velocity theta component<br> vx3: plasma velocity phi component<br> Bx1: magnetic field&nbsp;radial&nbsp;component<br> Bx2: magnetic field theta component<br> Bx3: magnetic field phi component</p> <p>Additionally the following derived variables are included:</p> <p>Jx1: electric current density radial&nbsp;component<br> Jx2: electric current density theta component<br> Jx3: electric current density phi component<br> Bpx1: plasma magnetic field radial&nbsp;component<br> Bpx2: plasma magnetic field theta component<br> Bpx3: plasma magnetic field phi component</p> <p>Plasma magnetic field means that part of the total magnetic field that results from the plasma interaction. It equals the total magnetic field subtracted by the homogeneous upstream field and Ganymede&#39;s intrinsic and induced field.</p> <p>All values are in normalized units with these normalization factors:</p> <p>NORMR = 2.631e8 &nbsp;cm<br> NORMV = 1.4e7 &nbsp;cm/s<br> NORMRHO = 1.661e-22 &nbsp;g/cm^3<br> NORMPRS = 3.255e-08 &nbsp;dyne/cm^2<br> NORMB = 6.395e-04 &nbsp;Gauss<br> NORMJ = 5.801e-03 &nbsp;statA/cm^2</p> <p>In Duling et al. 2022 we present results of a model sensitivity study. This dataset includes model output from our best guess setup (default setup) only.</p> <p>Since the data is in PLUTO&#39;s binary format &quot;flt&quot; we provide a Python code snippet that reads the data to data arrays.</p> <p><strong>grid.out</strong><br> This ASCII file contains the grid dimensions and coordinates of the cell boundaries.</p> <p><strong>data.0020.flt</strong><br> This binary file contains the simulation variables on the cell centers of the grid.</p> <p><strong>pluto.0.log</strong><br> This ASCII file contains the header of the PLUTO logfile.</p> <p><strong>read_data.py</strong><br> This Python code snippet helps with reading the data.</p>
