Stacked cross-correlation functions data for: Internal structure of the Mantle Transition Zone beneath the contiguous U.S.: Insights from the 520-km discontinuity revealed by ambient noise correlations.

This repository contains:Pre-processed ambient seismic noise cross-correlation function data (ccf_tempstack_0310_svd6_thresh000.hdf5)Stacked cross-correlation function data (output_400_520_0310_USSL2014)Picked depths for the d520 (depthconv_0310_400_520_USSL2014.hdf5)Picked depths for the d560 (depthconv_0310_400_560_USSL2014.hdf5)<br><br>associated with the paper Aiman et al. (2025), submitted to the Geophysical Research Letters (preprint available: https://essopenarchive.org/users/877771/articles/1270699-internal-structure-of-the-mantle-transition-zone-beneath-the-contiguous-u-s-insights-from-the-520-km-discontinuity-revealed-by-ambient-noise-correlations).<br>The pre-processed ambient seismic noise cross-correlation function data includes the cross-correlation function (CCF) data and station coordinates. For detailed information on the preprocessing and station details, please refer to the paper.<br>The d520 and d560 depth data include grid locations (longitude and latitude) and corresponding discontinuity depths. For a detailed description of the picking strategy, please refer to the paper. <br>The regionally stacked data is organized into folders, each corresponding to a specific profile measurement (e.g., 'N2600' represents a profile along 26 degrees latitude). Within each folder, data is stored in HDF5 format, with individual files containing regionally stacked cross-correlation functions for each grid point.
