We introduce a novel empirical model to forecast, 24 h in advance, the Total Electron Content (TEC) at global scale. The technique leverages on Global Ionospheric Map (GIM), provided by International GNSS Service (IGS), and applies nonlinear autoregressive neural network with external input (NARX) selected GIM grid points for single-point TEC forecasting, taking into account actual forecasted geomagnetic conditions. To extend forecasting scale, makes use of NeQuick2 Model fed an effective...

Earthquakes are the most energetic phenomena in lithosphere: their study and comprehension greatly worth doing because of obvious importance for society. Geosystemics intends to Earth system as a whole, looking at possible couplings among different geo-layers, i.e., from earth’s interior above atmosphere. It uses specific universal tools integrate methods that can be applied multi-parameter data, often taken on platforms (e.g., ground, marine or satellite observations). Its main objective is...
Abstract Many real‐life signals and, in particular, the space physics domain, exhibit variations across different temporal scales. Hence, their statistical momenta may depend on time scale at which signal is studied. To identify and quantify such variations, a time‐frequency analysis has to be performed these signals. The dependence of properties fluctuation scales distinctive character systems with nonlinear couplings among modes. assessing how statistics fluctuations vary will help...
