GIST: A tool for Global Ionospheric Tomography using GPS ground and LEO d ata and sources of opportunity with applications in instrument calibration
A. Flores, G. Ruffini, A. Rius +1
Ionospheric tomography using GPS data has been reported in the literature and even the application to radar altimeter calibration was succesfully carried out in a recent work. We h…

4D Tropospheric Tomography using GPS Estimated Slant Delays
A. Flores, G. Ruffini, A. Rius
Tomographic techniques are successfully applied to obtain 4D images of the tropospheric refractivity in a local dense network. In the lower atmosphere both the small height and tim…

A PIM-aided Kalman Filter for GPS Tomography of the Ionospheric Electron Content
Giulio Ruffini, Lidia Cucurull, Alex Flores +1
We develop the formalism for a PIM-based functional for stochastic tomography with a Kalman filter, in which the inversion problem associated with four-dimensional ionospheric stoc…
