The global core plasma model (GCPM) provides empirically derived cora plasma density and ion composition (H+, He+, and O+) as a function of geomagnetic and solar conditions throughout the inner magnetosphere. The model is based on data from DE/RIMS, DE/PWI, and ISEE/PWI and merges with the International Reference Ionosphere (IRI) at low altitudes. It is composed of separate models for the plasmasphere, plasmapause, trough, and polar cap.
Availability: Fortran model code is available from model authors.
