CMIT
There are several boundary layers to take into
consideration in space physics near the Earth. The solar
wind generates a shock at the outter boundary of the
magnetosphere. The inner magnetosphere affects auroral
activity at the ionosphere boundary, which drives certain
processes at the thermosphere. In order to better
understand these interactions, we have created
the Coupled Magnetosphere Ionosphere Thermosphere
(CMIT) model.
CMIT makes use of the following models:
- LFM - magnetosphere
solver for the ideal MHD equations
- Rice Convection Model (RCM)
- TIEGCM -
Thermosphere & Ionosphere solver
CMIT version 1.0 uses an OpenMP version of the LFM for
parallelism on multicore systems. CMIT version 2.0 is in
active development using an MPI version of the LFM for
message passing on a variety multiprocessor
supercomputers.
Model Coupling
We couple the LFM Magnetosphere model with the TIEGCM
Thermosphere model:
