This repository contains supplementary files to the manuscript ""Elevation-dependent periglacial and paraglacial processes modulate tectonically-controlled erosion of the Western Southern Alps, New Zealand" submitted to JGR: Earth Surface. It contains: - The Matlab script used to find the optimal distance-from-fault and elevation windows ("elevation_distance_window_optimization"), and 3 text files used for input in this script ("data_erates" contains the erosion rates, "data_elev" the number of pixels in each elevation bin, "data_distAF" the number of pixels in each distance-from-fault bin). - An Excel spreadsheet with the same information that the input text files contain, but specifiying the elevation or distance from fault bin values ("elevation and distance from fault with bins") - A shapefile of catchment outlines ("WSAcatch") for the catchments sampled for CRN denudation rates - Raw CRN data ("Table 2_new_CRN_data") - Excel spreadsheet with the compilation of themochronometric cooling ages used in the age2exhume code (van der Beek & Schildgen, 2023; https://doi.org/10.5281/zenodo.7341603). CRN data and catchment outlines will also be uploaded to the OCTOPUS database (https://octopusdata.org/) after manuscript acceptance.
