Global MHD simulation (REPPU) results for magnetosphere and ionosphere on 2006-10-18
收藏资源简介:
This contains 3D magnetospheric and 2D ionospheric data obtained by the global MHD simulation (REPPU) [Tanaka, 2015, doi:10.1002/9781118978719.ch13] with Level 6 for 2006-10-18. The VTK files (Visualization Toolkit format) contains physical variables in the magnetosphere and the ionosphere at 04:05:03 UT, 04:04:34 UT, and 04:04:05 UT on 2006-10-18. The VTK file can be opened by Visualization Toolkit, or 3-D visualization software packages like "VisIt", and "ParaView". The SAV file (IDL saveset format) contains physical variables in the ionosphere. The sav file can be opened by IDL. By typing for example IDL> restore,'tabiel-0106.sav'you can load the file to the memory of IDL. Type 'help' to confirm the variables that are loaded.
