Earth System Model Simulations of Ameriflux sites using dynamic roots and dynamic leaf to root allocation

This data package contains point-scale Earth System Model simulations run with DOE's E3SM Model. The package includes four sets of simulations, one set of simulations run in the default configuration, a second set of simulations run with the dynamic root module enabled, the third set with dynamic leaf to fine root allocation, and the fourth with the combination of dynamic roots and dynamic allocation. These simulations were run in point mode a Ameriflux sites, US-MMS, US-Moz, US-Syv, and US-NR1. These datasets can be used to assess the impact that dynamic roots have on Land Surface fluxes such as carbon and water. The simulations were run with atmospheric forcing from the Global Soil Wetness Project. We provide specifically here Gross Primary Production, Transpiration, relative root fraction per soil layer as well as Air Temperature, Precipitation and all the parameterizations used for the simulations. Our purpose for generating and analyzing these simulations was to assess the role that root dynamics and foraging for water has in the recovery timescale of ecosystems following climate perturbation. All data provided are in the "netcdf" format using standard CF-1 (Climate and Forecast) Convention. The data are all machine readable using various software platforms including Matlab, NCO, Panoply and R.本数据集包含基于美国能源部（Department of Energy, DOE）E3SM模式（E3SM Model）运行的点尺度地球系统模式（Earth System Model）模拟结果。本数据集共包含四组模拟试验：第一组采用默认配置运行；第二组启用动态根系模块运行；第三组配置动态叶片至细根分配机制；第四组同时启用动态根系与动态分配机制。所有模拟均以点尺度模式运行于Ameriflux站点（Ameriflux sites），具体站点包括US-MMS、US-Moz、US-Syv及US-NR1。本数据集可用于评估动态根系对碳、水等陆地表面通量（Land Surface fluxes）的影响。模拟所用的大气强迫数据来自全球土壤湿度项目（Global Soil Wetness Project）。本数据集具体提供总初级生产力（Gross Primary Production, GPP）、蒸腾作用（Transpiration）、各土层相对根占比，以及气温（Air Temperature）、降水（Precipitation）与模拟所用的全部参数化方案（parameterizations）。本次开展模拟并构建数据集的初衷，是评估根系动态与水分觅取过程在生态系统受气候扰动后的恢复时间尺度中所发挥的作用。所有数据均采用"netCDF"格式存储，并遵循CF-1（Climate and Forecast，气候与预报）标准公约。本数据集可通过多种软件平台读取，包括Matlab、NCO、Panoply及R语言。
