the solar magnetic field and the EIT-based temperature map

The quasi-steady states of the three-dimensional global solar corona
obtained with the time-dependent MHD simulation are presented.
The synchronic frame format of solar magnetic field and the
SOHO/EIT-based coronal temperature map are used as the boundary
constraints, so that the pressure balance between the coronal plasma and
magnetic field will be realistically simulated and thus the obtained
three-dimensional simulation data will better represent the structures
of the solar coronal at the time of interest.
Our MHD code employs the concept of the projected normal characteristic
method
to include these measurement-based data as the sub-Alfvenic numerical
boundary conditions without numerical instability.
