AB: The Rice Convection Model (RCM) is a multi-fluid model of the plasma and electric field distributions of Earth's inner and middle magnetosphere. For computational ease, the RCM was originally formulated assuming that the planetary magnetic dipole axis was aligned with the rotation axis of the planet. Over the years several people have persisted in pointing out that, contrary to these assumptions, the intrinsic magnetic field of the Earth is not a simple magnetic dipole aligned with the rotation axis. While the planetary magnetosphere we have been modeling with the RCM has many Earthlike features, the assumed internal magnetic field geometry is not one of them. Accordingly, we have reformulated the RCM to accept a more general and realistic internal magnetic field. Such a reformulation is necessary in order to realistically include longitude/UT and seasonal effects in the RCM and to properly interface the RCM with global scale thermosphere/ionosphere models. We describe the reformulation of the model, the Euler-potential-based coordinate system used in the reformulated RCM, and early results of the new code.
