WSA-ENLIL+Cone Modeling of CMEs in 2010-2011 Using Multipoint Spacecraft Observations

From July 2010 to December 2011, the separation of Solar Terrestrial Relations Observatory (STEREO) A/B from Earth gradually increased from 70^o to 110^o, and the twin spacecraft provided two critical vantage points to monitor the Sun and solar wind in additional to the spacecraft near the Earth orbit. On the other hand, the Solar Dynamics Observatory (SDO) launched in early 2010 enabled in-depth observations of the CME source regions. For selected CMEs in this period, including wide CMEs encountered by more than one spacecraft, we use the Stereoscopic CME Analysis Tool (StereoCAT), NOAA Space Weather Prediction Center (SWPC)'s CME Analysis Tool (CAT), and Graduated Cylindrical Shell (GCS) model to fit the coronal observations of CMEs as accurately as we can. Using these CME parameters and considering their uncertainties, we run the new version of Wang-Sheeley-Arge (WSA) - ENLIL + Cone modeling system using the time-dependent photospheric magnetograms. We systematically assess the effects of the CME input from different fitting methods to the CME modeling result and discuss the ways to improve the model performance. The results will provide vital insights into the use of future missions at new observing locations such as L5 for the space weather research and forecasting.
