TIEGCM October 18, 1995 Storm Simulation

October 1995 Storm Event:

On October 18, 1995, an interplanetary magnetic cloud encountered the Earth and consequently induced a major magnetic storm as well as massive substorms (with the maximum magnitude of Dst reaching 120 nT and AE reaching 1600 nT). The realistic time-dependent high-latitude ionospheric convection and auroral precipitation patterns derived from the AMIE procedure was used as inputs to the NCAR-TIEGCM to simulate the ionospheric/thermospheric response to the storm. The TIEGCM ran in a 5-min time step, and the TIEGCM history volumes were recorded every 10 mins. For the period of October 18-19, 1995, the 2-day average solar radiation index Sa was 80x10^-22 W/m^2Hz.
