Abstract : Significant research effort has been directed at global ionospheric specification using the UML-operated Global Ionospheric Radio Observatory (GIRO). In 2010, GIRO continued acquisition and dissemination of both real-time and retrospective knowledge of electron density profile (EDP) in the ionosphere from 64 digisonde locations around the world. Highly accurate, manually validated EDP records from GIRO were used to calibrate DMSP F18 UV sensors and quantify errors introduced by the horizontal smear of COSMIC radio occultations. Comparative analysis of the profile inversion algorithms against incoherent scatter radar measurements has identified a deficiency of the POLAN technique used in QualScan software involved in EDP uncertainty analysis for AFWA. The utility of the high-resolution and high cadence Doppler skymaps in characterizing the plasma velocity profile in the heated region above HAARP has been clearly established. Specification of D region absorption from Digisonde measurements has proven to be highly sensitive and thus able to detect and model M-class flare events.
