 Abstract: The Earth's plasmasphere is a dynamic region of dense plasma with itssource in the ionosphere. Accurate knowledge of the plasma densitydistribution and boundaries are important for the accurate modeling ofthe radiation belts and ring current growth and decay mechanisms. Theplasmasphere densities can be determined in many ways, from space andfrom the ground. However almost all such observations are limited topoint observations or single flux tube observations. For completeknowledge the regions between observations must be filled in with amodel. The combination of a model with observations to obtain anoptimal global map is called data assimilation. We will show someresults which combine a simple plasmasphere model, the Dynamic GlobalCore Plasma Model with a variety of observations in an EnsembleKalman Filter framework to produce maps of the global plasma densitydynamics. These maps are then compared with in-situ spacecraftobservations for validation.
