  2. Computer simulation data and satellite observation data are expressed in one view frame. POLAR VEMS (Virtual Earth’s Magnetosphere System) Computersimulation data Satelliteobservation data AKEBONO POLAR/VIS (1) Convert of data format GOES9 GOES8 (2) Preprocess of data (re-sampling) (3) Visualize in 4-D Pressure (Global MHD simulation) (4) Interactive analysis An example view of VEMS VEMS

  3. Fluxrope Global MHD simulation (1/2)global view

  4. Global MHD simulation (2/2)field lines surrounding the fluxrope
