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)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).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.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. 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.
