Magnetic field-aligned electron-density (Ne) profiles can be calculated from active soundings using the Radio Plasma Imager (RPI) on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite. By observing these profiles under different geomagnetic conditions, the underlying physics that control the Ne distribution can be investigated. In this presentation RPI observations will be used to show that a magnetic field line depleted of plasma has an Ne distribution approximating a collisionless (CL) profile, while a saturated field line has a diffusive equilibrium (DE) profile. Furthermore, by using the RPI-derived profiles it is possible to observe the transition from the depleted CL profile to the saturated DE profile. Using computationally simple CL and DE models as upper and lower boundaries respectively, methods to vary the distribution between these two extremes that reproduces the refilling of the field-aligned Ne profiles observed by RPI will be presented. Furthermore, the results of this approach will be compared with the Multi-Species Kinetic Plasmasphere Model (MSKPM), a kinetic field-aligned model that simulates the plasmaspheric refilling by single particles from the underlying exosphere. Comparisons of the Global Plasmasphere Ionosphere Density (GPID) model with IMAGE Ne observations from passive and active RPI operations will demonstrate the increased accuracy of GPID when the improved CL-DE field-aligned Ne distribution is included in the model.
