Accurately imaging the 3-D ionospheric variation and its temporal evolution has always been a challenging task for the space weather community. Recent decades have witnessed tremendous steps forward in implementing ionospheric data assimilation, with the rapid growth of ionospheric data availability from multiple ground-based and space-borne sources. This presentation will describe a new TEC-based ionospheric data assimilation system (TIDAS) for 3-D regional ionospheric imaging. TIDAS can yield high-fidelity altitude-resolved electron density distribution in the target region, which is a powerful tool for better specification and understanding of ionospheric dynamical variations, as well as for space weather.
