Space systems. Space environment (natural and artificial). The Earth’s ionosphere model: international reference ionosphere (IRI) model and extensions to the plasmasphere Ingestion-build-981921 Scope This International Standard provides guidance to potential users for the specification of the global distribution of ionosphere densities and temperatures, as well as the total content of electrons in the height interval from 50 km to 1 500 km. It includes and explains several options for a plasmaspheric extension of the model, embracing the geographical area between latitudes of 80S and 80N and longitudes of 0E to 360E, for any time of day,
