Supplementary data for Global potential risk of thallium in topsoil: A cropland-focused quantification framework

Maps of the global distribution of Tl accumulation risk and concentrations in topsoil are provided here. The first file, 'Tl_1ppm_predicted_class1_probability.tif', is the result map generated by the CatBoost classification model. Specifically, the value of each grid point represents the probability that the topsoil Tl concentration in this grid is greater than 1 mg/kg. The second file, 'Tlpredicted_concentrationR_Cat.tif', is the result map generated by the CatBoost regression model. Specifically, the value of each grid point represents the topsoil Tl content (mg/kg) in this grid.
