Depth-dependent freeze-thaw controls on near-surface shear-wave velocity revealed by ambient-noise distributed acoustic sensing

This dataset contains daily stacked ambient-noise DAS (distributed acoustic sensing) data used in the manuscript "Depth-dependent freeze-thaw controls on near-surface shear-wave velocity revealed by ambient-noise distributed acoustic sensing" . Each file is a MATLAB .mat file named as YYYYMMDD_vsg.mat, representing the daily stacked cross-correlation functions with a time sampling interval (dt) of 5e-4 s and a spatial sampling interval (dx) of 2.0422 m.The data are processed from raw DAS recordings following the workflow described in the manuscript. The files are organized by date and can be loaded using load('YYYYMMDD_vsg.mat'). Please cite the corresponding paper when using this dataset.
