Spectral Signatures of Fourier Amplitude Spectra for Ground Motion Characterization in Tectonically Complex Regions (Southern Italy): Data and Reproducibility Archive

This repository contains the datasets, geospatial products, and reproducibility material supporting the manuscript "Spectral Signatures of Fourier Amplitude Spectra for Ground Motion Characterization in Tectonically Complex Regions (Southern Italy)". The archive includes the derived products of the generalized inversion analysis, including event, path , and site residual terms, variance components, spectral-signature clustering results, PCA and path-cell inversion products, author-defined macrodomains and microdomains, focal mechanisms, and reference-site datasets. To facilitate transparency and reproducibility, the repository also provides the Python scripts, configuration files, metadata, provenance documentation, and software environment required to reproduce the archived analyses and selected manuscript figures. The release has been organized as a self-contained, archive-relative workflow with documented provenance, integrity checks, and machine-readable metadata. All original event, station, and component identifiers are preserved to ensure traceability of the published results. Detailed information on the dataset structure, file descriptions, processing workflow, reproducibility, known limitations, and licensing is provided in the accompanying README.md.
