 Fok's CIMI model is currently being used to predict the fluxes observed by the Van Allen Probes.CIMI takes in information about magnetic fields, electric potentials, quiet-time conductances and solar wind speed, and outputs information about ion fluxes, plasmasphere density and ionspheric potentials.Using the model Fok found that the main phase pressure of the magnetosphere was not created by the solar wind, but instead dominated by energetic protons from the plasmasphere.
