Abstract
The accuracy of OMNI dataset being propagated to bow shock nose and used to represent geomagnetic storms is a known issue. Inaccuracies of this data bring erroneous results in scientific endeavors therefore establishing the importance of accuracy and consistency. This case study examines the accuracy of the OMNI data and data near-Earth in representing geomagnetic storms with different drivers on global simulations. This research will include examples of global magnetosphere simulations, such as SWMF, driven with two storms driven by coronal mass ejections, and one driven by a high-speed stream using OMNI data and data near-Earth to illustrate potential variations in global simulation output during geomagnetic storms. Expected results from this study are that well correlated OMNI leads to well simulated geomagnetic storms and likewise poor correlated OMNI leads to chaotic random simulated geomagnetic storms. Results show that the percent differences for Dst, AE, and cpcpn seem to increase inversely with CC regarding the CME events.
