Steps to reproduce

Download all files. Use MATLAB to run the scripts "Flux_Calibration_Demo.m" and "Flux_Calculation_Demo.m" to reproduce the respective saltation flux calibration and calculation processes. All dependency data files and functions are contained in this dataset. (NOTE: These scripts were tested using MATLAB R2017b.)
