Open Numerical Simulation Data of Planetary Magnetosphere

For a number of years, we have performed the 3-dimensional magnetohydrodynamic (MHD) simulations of Jovian, Kronian and Terrestrial magnetospheres to examine the dynamics and configuration using the several supercomputer systems. The size of latest simulation data becomes over 1TB/timestep and we store a lot of data in the supercomputer system. However, we do not open the simulation data due to the access limitation of supercomputer storage system. Recently thanks to the developments of the storage system, we can store the simulation data in the network storage system where can be accessed through the Internet. Considering this situation, we have started to develop the open database of our planetary magnetospheric simulation data for the collaboration of observation and machine learning. In this database, we store the multi solar wind parameters survey simulation data to see the effect of solar wind to the magnetosphere. In addition, simulations using Juno observation data for about one month are stored to compare with Hisaki and Juno observations. Thanks to the recent progress in supercomputer systems, we have obtained the capability to simulate planetary magnetosphere with 1000 times the number of grid points as compared to our simulation size in 10 years ago. This has allowed us to combine the high-resolution global simulation with a micro-scale simulation of the Jovian magnetosphere. For the first time, we have been able to resolve Kelvin Helmholtz waves on the magnetopause in these high-resolution simulations. The size of these high-resolution data is huge (3TB/sampling) so that it is hard to download. To overcome this difficulty, we will introduce the new transfer protocol to the storage system. In this study, we show the database of planetary magnetospheric simulation data and its status.
