Query: Chromosphere to 1 AU Simulation of the 2011 March 7th Event: A
  Comprehensive Study of Coronal Mass Ejection Propagation   We perform and analyze results of a global magnetohydrodyanmic (MHD)
simulation of the fast coronal mass ejection (CME) that occurred on 2011 March
7. The simulation is made using the newly developed Alfv\'en Wave Solar Model
(AWSoM), which describes the background solar wind starting from the upper
chromosphere and extends to 24 R$_{\odot}$. Coupling AWSoM to an inner
heliosphere (IH) model with the Space Weather Modeling Framework (SWMF) extends
the total domain beyond the orbit of Earth. Physical processes included in the
model are multi-species thermodynamics, electron heat conduction (both
collisional and collisionless formulations), optically thin radiative cooling,
and Alfv\'en-wave turbulence that accelerates and heats the solar wind. The
Alfv\'en-wave description is physically self-consistent, including
non-Wentzel-Kramers-Brillouin (WKB) reflection and physics-based apportioning
of turbulent dissipative heating to both electrons and protons. Within this
model, we initiate the CME by using the Gibson-Low (GL) analytical flux rope
model and follow its evolution for days, in which time it propagates beyond
STEREO A. A detailed comparison study is performed using remote as well as
\textit{in situ} observations. Although the flux rope structure is not compared
directly due to lack of relevant ejecta observation at 1 AU in this event, our
results show that the new model can reproduce many of the observed features
near the Sun (e.g., CME-driven extreme ultraviolet (EUV) waves, deflection of
the flux rope from the coronal hole, "double-front" in the white light images)
and in the heliosphere (e.g., shock propagation direction, shock properties at
STEREO A).
