International Reference Ionosphere-IRI 79: Report of URSI Working Group G.4 (Identical with COSPAR Task Group on International Reference Ionosphere)

摘要

This report is the second edition of the International Reference Ionosphere (IRI) succeeding the first one, IRI 1978, and edited by the International Scientific Radio Union (URSI). The aim of the IRI is to establish a summary compendium of height profiles through the ionosphere for the four main plasma parameters, namely: plasma density, plasma temperatures of electrons and ions, and ion composition. These parameters are generated from a descriptive model containing reliable data that can be extracted and used to obtain average profiles. The IRI-generated parameters compare well with COSPAR International Reference Atmosphere (CIRA) values (last edition CIRA 1972). The emphasis of IRI is to summarize reliable experimental data when available.
