Center for Integrated Space Weather
- Dartmouth's CISM research is focused on the earth's magnetosphere and the
related aspects of space weather. Specifically, we aim to develop a
computational module representing the Earth's magnetosphere, including the inner
plasma sheet, ring current, and Birkeland, or magnetic field aligned, currents.
This module will be based on the Lyon-Fedder-Mobarry 3D Magnetospheric code, but
will be designed to connect to the Rice Convection Model in the inner
magnetosphere and also the Thermosphere-Ionosphere Nested Grid (TING) version of
the NCAR TIMED-GCM model of the ionosphere and thermosphere. The module will
accept as inputs time-dependent magnetic field and plasma densities and
temperatures at the outer boundary. The RCM will compute the distribution
functions of plasma within its domain and feed the information back to the
global MHD model. Likewise, TING will provide an ionospheric boundary condition
for the LFM code. The LFM code, modified by the RCM, will also compute the
magnetic field-aligned currents into the ionosphere.
