ScodaKit: A scientific Python-based command line toolkit for S-coda seismic wave analysis and scattering parameters estimation

ScodaKit is an open-source command-line pipeline for estimating the scattering parameters of S-coda waves from seismic waveform data. It combines waveform downloading, manual seismic phase picking, catalog metadata merging, coda window extraction, energy decay analysis and visualization — all within a modular and extensible architecture.

Designed for researchers, seismologists, and geophysicists working on seismic attenuation, crustal scattering, or seismic coda-based energy models.

🛠️ Features

This command-line pipeline allows you to:

• 📡 Download waveform data from FDSN-compliant data centers (e.g., NOA, IRIS)
• ⌛ Manual picking of P and S seismic wave arrivals using interactive seismic waveform viewers
• 🗃️ Merge waveform arrival data with seismic event metadata
• 🌍 Generate interactive or GIS-compatible maps of events and stations
• 🧠 Extract S-coda waveforms from the seismic traces using signal to noise ratio (SNR) method
• 📉 Analyze S-coda energy decay to estimate mean free path (ℓ) and Coda attenuation factor (B) using the Single Isotropic Scattering Model
• 📊 Visualize full waveforms, spectrograms and coda windows
• 🧪 Modular stages via CLI for reproducible research
