Global climatological maps of ionospheric parameters from recent satellite missions
Abstract
Satellite observations have always been crucial in determining and regularizing the IRI model by providing global data bases for empirical models. Special attraction may have local time precessing, polar orbiting satellites which cover the Earth ionosphere from polar to equatorial regions at all local times and longitudes. Out of these, CHAMP is a successful example with a presently unique orbit altitude of 400 km, and a live time and continuous data base of 10 years at the time of COSPAR 2010. We want to present results of global climatologies on plasma parameters, such as electron density and temperature and emphasis their special characteristics. CHAMP magnetic field and electron density observations have also enabled the statistical global review of the occurrence rates of equatorial plasma irregularities. Even enhanced knowledge on the climatological distribution of these parameters is expected from multi-spacecraft satellite missions, such as is the upcoming ESA Swarm mission. It will provide a multitude of ionospheric and magnetospheric parameters, such as plasma densities and temperatures, the electric and the magnetic field, neutral density and wind, as well as GPS Total Electron Content at three satellites in two different altitudes. We will present products and scientific possibilities arising from the Swarm mission in view of enriching the development of empirical models.
