The inner magnetosphere as simulated by the anisotropic BATS-R-US - CRCM model

We have recently developed the two-way coupling between anisotropic BATS-R-US and the CRCM. The coupled model provides us an opportunity to examine the effects of pressure anisotropy on the inner magnetospheric dynamics self-consistently, especially during geomagnetic disturbed time. From the aspect of the CRCM, we investigate the differences between the isotropic-MHD-driven and anisotropic-MHD-driven simulations. We validate the coupled model through comparing the simulated pressure anisotropy, energy flux and other model outputs with TWINS and other satellite observations.
