||The primary goal of this project is to combine the OpenGGCM (Open Geospace General Circulation Model)
with the NCAR Data Assimilation Research Testbed (DART), which implements an Ensemble Kalman Filter (EnKF)
and will enable the sequential assimilation of ionosphere, thermosphere, and magetosphere data.
We will also optimize model parameters by including them into the state vector.
This will improve model accuracy even when no data are assimilated.

Open Geospace General Circulation Model
Information about OpenGGCM:
- Coupled global magnetosphere - ionosphere - thermosphere model.
- 3d Magnetohydrodynamic magnetosphere model.
- Coupled with NOAA/SEC 3d dynamic/chemistry ionosphere - thermosphere model (CTIM).
- Coupled with inner magnetosphere / ring current models: Rice U. RCM, NASA/GSFC CRCM.
- Model runs on demand (>500 so far) provided at the Community Coordinated Modeling Center
(CCMC at NASA/GSFC). http://ccmc.gsfc.nasa.gov/
- Fully parallelized code, real-time capable. Runs on IBM/datastar,
IA32/I64 based clusters, PS3 clusters, and other hardware.
- Used for basic research, numerical experiments, hypothesis testing, data analysis support,
NASA/THEMIS mission support, mission planning, space weather studies, and
Numerical Space Weather Forecasting in the future.
- Funding from NASA/LWS, NASA/TR&T, NSF/GEM, NSF/ITR, NSF/PetaApps, AF/MURI programs.
