Abstract

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 profiles from CHAMP are compared with Canadian Advanced Digital Ionosonde (CADI) measurements at two vertical sounding stations well within the Polar Cap, Eureka (geog. 80130 N; 86110 W) and Resolute Bay (geog. 74410 N; 94540 W). We compared the ionospheric parameters such as the peak electron density of the F-layer (NmF2) and the peak height of the F-layer (hmF2) for a 3-year period, 2004–2006. CHAMP derived NmF2 shows reasonable agreement with the ionosonde retrieved NmF2 for both the stations (0.76 and 0.71 correlation coefficient, for Eureka and Resolute Bay, respectively) whereas the hmF2 agreement is not that acceptable (0.25 and 0.37 correlation coefficient, respectively). The hmF2 from vertical sounding showed less spread than the CHAMP hmF2.
