The Center for Integrated Space Weather Modeling (CISM) is working on developing
a comprehensive geospace model. The core of this models is composed of three
components. The interaction between the magnetosphere and a solar wind is
simulated by the Lyon-Fedder-Mobarry global magnetospheric (LFM) model. The
inner magnetosphere is simulated by the Rice Convection Model (RCM). Response
of the ionosphere-thermosphere system to magnetospheric driving is simulated by
the Thermosphere Ionosphere Nested Grid (TING) Model. We begin with a brief
discussion of these three models are coupled together. In the current
configuration, the LFM acts and as an intermediary between the other geospace
models. It determines the particle fluxes and electric field inputs to the TING
model by using its inner magnetospheric state as modified by the Rice convection
model. The LFM also supplies magnetic field and plasma information to the RCM.
The RCM also needs ionospheric conductivity information which as passed to it
from TING via the LFM. Next, we'll compare results from the individual models
to results from the coupled model for an interval of steady southward IMF that
includes a magnetospheric substorm. Finally, we'll address the need for
measurements throughout the system to quantify the accuracy of the coupled
model.
