Freeze–Thaw Controls on Dissolved Organic Carbon Export: A Numerical Investigation of Hydrological Mechanisms in a Hillslope

The dataset includes all necessary input files for running the Advanced Terrestrial Simulator (ATS), such as the mesh file, meteorological forcing data, input scripts, and geochemical model files. The output files contain daily time-series results of key variables at the outlet, including groundwater discharge, geochemical concentrations such as dissolved organic carbon and dissolved oxygen.
