abstract = "Prompt and accurate imaging of the ionosphere is essential to
space weather services, given a broad spectrum of applications
that rely on ionospherically propagating radio signals. As the 3D
spatial extent of the ionosphere is vast and covered only
fragmentarily, data fusion is a strong candidate for solving
imaging tasks. Data fusion has been used to blend models and
observations for the integrated and consistent views of
geosystems. In space weather scenarios, low latency of the sensor
data availability is one of the strongest requirements that limits
the selection of potential datasets for fusion. Since remote
plasma sensing instrumentation for ionospheric weather is complex,
scarce, and prone to unavoidable data noise, conventional 3D-var
assimilative schemas are not optimal. We describe a novel
substantially 4D data fusion service based on near-real-time data
feeds from Global Ionosphere Radio Observatory (GIRO) and Global
Navigation Satellite System (GNSS) called GAMBIT (Global
Assimilative Model of the Bottomside Ionosphere with Topside
estimate). GAMBIT operates with a few-minute latency, and it
releases, among other data products, the anomaly maps of the
effective slab thickness (EST) obtained by fusing GIRO and GNSS
data. The anomaly EST mapping aids understanding of the vertical
plasma restructuring during disturbed conditions.",
