Summary:Relying on the well-proven formalism of the International Reference Ionosphere (IRI) model, an IRI Real-Time Assimilative Mapping (IRTAM) extension is being developed at the Space Science Laboratory (SSL) University of Massachusetts Lowell. The IRTAM uses measurements from the Global Ionosphere Radio Observatory (GIRO) and knowledge about ionospheric climatology to now-cast global ionospheric weather. This work presents the results of the validation of current assimilative technique based on "morphing". This technique morphs the climatology empirical model, IRI, with the current ionospheric conditions data by introducing corrections for expansion coefficients rather than in the domain maps. Global, time-dependent mapping of two main ionospheric characteristics, F2 layer peak density and peak height, has been implemented in IRTAM.
