A suggested model for the IRI plasmapheric distribution
A model has been constructed which grafts IRI topside profiles to field-aligned diffusive equilibrium profiles at a “reference level” near 650 km altitude. For different values of geographic latitude, longitude, sunspot number, season and time, the properties of the plasma distribution in the equatorial plane are investigated. These are compared with observations made by satellite (particularly GEOS and ISEE) and also with deductions made from whistler observations.
