Code and Dataset for Ambient Seismic Noise

This repository contains the core MATLAB scripts and the observational datasets used to execute the Iterative Ensemble Kalman Inversion (I-EKI) framework presented in the manuscript: "Monitoring of a Seasonal Freeze-Thaw Cycle Soil Through Ensemble Kalman Inversion of Ambient Seismic Noise". 1. Datasets Included:In addition to the code, this archive provides the underlying data supporting the findings of the study: Field Monitoring Data : This file contains the processed time-lapse ambient seismic noise. It captures the continuous spatiotemporal dynamics of the seasonally frozen soil over the monitoring period and serves as the primary observational input for the inversion results discussed in the manuscript. 2. Software/Code Description:The core I-EKI algorithm and statistical post-processing scripts are fully provided herein. However, the specific forward modeling function used to compute theoretical dispersion curves (calcmulti.m) is temporarily withheld from this public archive due to ongoing licensing constraints. To run this script out-of-the-box, users can either: Contact the code author at [e-mail] to request a copy of calcmulti.m. Seamlessly substitute the function forward_wrapper_calcmulti_real with any standard open-source surface wave forward modeling routine (e.g., CPS by Herrmann, Geopsy). The EKI architecture is independent of the specific forward solver chosen.
