ATS (Advanced Terrestrial Simulator) integrated hydrology and reactive transport model output in Copper Creek, Colorado

This dataset is generated using the ATS (Advanced Terrestrial Simulator) model at Copper Creek, Colorado, the largest catchment in the East River watershed. ATS is an integrated hydrology and reactive transport model to simulate the Concentration-Discharge (C-Q) relationship, and is used to quantify the geochemical export and understand how watersheds respond to climate disturbances. Key hydrogeochemical variables, including discharge, precipitation, evapotranspiration, and geochemical concentrations, were simulated and output at a daily frequency at the Copper Creek outlet. A group of hydrology and geochemical model variables over the spatial domain are output at a bi-monthly frequency. The model used 1-km resolution daily frequency Daymet meteorological forcing, and mineral composition from previous studies. The simulations are performed on NERSC. The datasets include the input files for running the ATS (Advanced Terrestrial Simulator) simulation, including the mesh file, input script and geochemical model files. The output files from the ATS (Advanced Terrestrial Simulator) are the daily time-series discharge and geochemical concentration simulated at the outlet of Copper Creek, and the bi-monthly spatial output over the simulation domain.

本数据集基于科罗拉多州铜溪（Copper Creek）——东河流域最大集水区——的先进陆地模拟器（Advanced Terrestrial Simulator, ATS）模型生成。ATS是一款集成水文与反应性输运模型，可用于模拟浓度-流量（Concentration-Discharge, C-Q）关系，量化地球化学输出通量，并解析流域对气候扰动的响应机制。研究团队在铜溪出口处以日尺度频次模拟并输出了流量、降水、蒸散发及地球化学浓度等关键水文地球化学变量；同时以双月频次输出模拟空间域内的一组水文与地球化学模型变量。本模拟采用分辨率为1公里的Daymet日尺度气象强迫数据，以及前人研究已发表的矿物组分作为模型输入参数。所有模拟工作均在美国国家能源研究科学计算中心（National Energy Research Scientific Computing Center, NERSC）完成。本数据集包含运行ATS模拟所需的全部输入文件，涵盖网格文件、输入脚本及地球化学模型文件；ATS模拟生成的输出文件包括两类：一是铜溪出口处的日尺度时间序列流量与地球化学浓度数据，二是模拟域内的双月空间输出结果。
