Scientific paper

With the innovative observational techniques employed by CLUSTER and IMAGE spacecraft, new light has being shed on the plasmasphere. This presentation reviews some recent progress made in plasmaspheric physics-based models on the basis of these modern observations. In particular, dynamical simulations have been developed to study the mechanisms of plasmapause formation and the influence of the electric field evolution during geomagnetic storms. The position of the plasmapause is determined as a function of the level of geomagnetic activity. The deformation of the plasmasphere during quiet and disturbed geomagnetic periods is illustrated. The dynamic model has been generalized in three dimensions and is constrained by realistic data. The core of the plasmasphere is obtained from the kinetic exospheric approach assuming a kappa velocity distribution function for the particles. The relative abundance of trapped particles is constrained in such way that the density profiles correspond to Carpenter and Anderson (1992) observations. Model predictions are compared with the results of other plasmaspheric models and observations of IMAGE and CLUSTER.
