ResourceID spase://NASA/NumericalData/UCLA/Global-MHD-code/PT10S Description The simulation outputs are asci files containing out from the MHD simulation mapped to the minimum magnetic field surface in the magnetotail during the March 14,2008 substorms. There is one time in each file and 2161 files each separated by 10s. The results span 6 hours from 0200 to 0800. The results are in GSM coordinates.
