    Monitoring of Ionospheric Anomalies Using GNSS Observations to Detect Earthquake Precursors by Nicola Perfetti, Yuri Taddia, Alberto Pellegrinelli

    Published 2025-01-01
    “…In this study, we outline a strategy to estimate the VTEC in real-time, its rate of change, and the corresponding Signal-to-Noise Ratio (SNR) based on dual-frequency GNSS Doppler observations. We describe how to compute these parameters from GNSS data for a regional network using Adjusted Spherical Harmonic Analysis (ASHA) applied to a local model. …”
