AB: As part of the space environment modeling activities of the Center for Integrated Space Weather Modeling (CISM), we have been developing a coupled model that merges the Rice Convection Model (RCM) of the inner magnetospheric model with the Lyon-Fedder-Mobary (LFM) global MHD model of the magnetosphere. We present preliminary results from the coupled code where the LFM provides magnetic and electric fields, ionospheric conductivities, and plasma distributions to the RCM; the RCM then returns to the LFM updated plasma quantities. Using results from the coupled code with idealized inputs and varied coupling algorithms, we discuss the inner magnetosphere effects of this coupled model, such as the formation of region-2 field aligned currents, electric field shielding and ring current formation, as well as the response of the global magnetosphere, such as the magnetic field and cross polar cap potential.
