Abstract
We develop a PIM-based functional for stochastic tomography with a Kalman filter, which aids in the regularization of the inversion problem associated with 4D ionospheric stochastic tomography. We let the GPS data select dynamically the best PIM parameters, in a 3DVAR fashion. We collect GPS data from GPS/MET and IGS for one of the World Space Days and we ingest them in a Parameterized Ionospheric Model (PIM). The process selects the ionospheric parameters that best fit the PIM model. We then compare our deduced ionospheric parameters with the values provided by the US National Geophysical Data Center. The resulting PIM-fitted model is compared to direct 3D voxel tomography. We demonstrate the value of this method analyzing IGS and GPS/MET GPS data.
