Comparison of the CHAMP radio occultation data with the Canadian advanced digital ionosonde in the Polar Regions
In this paper we present the results of the comparison of the retrieved electron density profiles of the Ionospheric Radio Occultation (IRO) experiment on board CHAMP (CHAllenging Minisatellite Payload), with the ground ionosonde profiles for the Polar Regions. IRO retrieved electron density profile...
