Ιonospheric tomography

The combination of different types of data (GNSS, DORIS), and with different geometries (ground-based, upward / downward LEO-based, vessel-based) allows a further improvement of the global ionospheric tomography in general, and the VTEC GIM in particular (Hernández-Pajares et al. 2020).
