GNSS Coordinate Difference Datasets and MATLAB Analysis Codes for Pre-seismic Spectral Analysis (Noto 2024 and Maule 2010 Earthquakes)

This repository contains the processed GNSS coordinate difference datasets (Δλ, Δφ, Δh), receiver clock offset and zenith tropospheric delay time series derived from CSRS-PPP processing, along with MATLAB analysis codes implementing median filtering, linear detrending, Continuous Wavelet Transform (Morse wavelets) and Z-score anomaly detection. Data correspond to the 2024 Mw 7.5 Noto Peninsula (Japan) and 2010 Mw 8.8 Maule (Chile) earthquakes, as described in the associated manuscript submitted to JAMES.
