EOMF-25. Analysis of the Performance of WAM-IPE model during November 2003 Super Geomagnetic Storm
The paper highlighted the performances of Weimer model driven coupled Whole Atmosphere Model Ionosphere Plasmasphere Electrodynamics (WAM-IPE) during the super geomagnetic storm on November 20, 2003 (minimum SYMH = -490nT). The northern hemispheric cross polar cap potential from the Weimer model was maximum near 15-16UT, which was correlated with the negative transition of Interplanetary Magnetic Field (IMF) Bz. The model underestimated the E×B plasma drifts from Defense Meteorological Satellite Program (DMSP) satellites at an altitude of 850 km. But the model showed overestimation in the vertical drifts and Total Electron Content (TEC) near the equatorial region. The performances of the model towards predicting the thermospheric O/N2 is also observed and compared with NASA Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) Global Ultraviolet Imager (GUVI) O/N2 data. These results are shown in this paper.
