This dataset is a compilation of all published denudation rates derived from in-situ cosmogenic radionuclides as of 2016. All sites have been geo-referenced (WGS 84). Geo-referenced locations are then used to extract the yearly aridity index for each site from the CGIAR global Aridity dataset (https://cgiarcsi.community/data/global-aridity-and-pet-database/). Denudation rates are used to calculate Soil Production rates, soil flux and diffusivity (volumetric and mass) and hillslope residence times. Along with climate and denudation, the lithology reported for each site was used to derive two estimates of rock strength. For a full description of the methods used to calculate the values, please see the dissertation submitted by the same author (4/2018). Fields which are flagged in yellow indicate errors in the published rates. values in bold indicate that a missing value was replaced with the column mean (esp. bulk densities). Slopes which were reported as zero have been replaced by a value of 0.01 for the purposes of calculating slope-dependent values (e.g. flux).
Studies were obtained from a thorough literature search. Search was conducted from 2015-2016. Search words were ``Soil production", ``Cosmogenic Radionuclide", and ``Denudation". Criteria for inclusion in the dataset were the following: 1.) Denudation must have been determined using in-situ CRNs and some must have been determined under soil/saprolite cover 2.) Studies had to provide a location (either lat/long or a map which allowed for an approximate location to be determined) 3.) Studies had to explicitly list the soil depths overlying each CRN inventory 4.) Studies were excluded which relied primarily on catchment averages (derived from detrital CRN inventories)
