Dynamic Vegetation Model Dynamic Organic Soil Terrestrial Ecosystem Model (DVM-DOS-TEM) simulations for a 50x50 km2 area centered on eight mile lake, Alaska and Toolik Field Station, Alaska [1950-2100]

This set of files store model simulations using the biosphere model Dynamic Vegetation Model Dynamic Organic Soil Terrestrial Ecosystem Model (DVM-DOS-TEM), developed to represent the effect of deep nitrogen acquisition by the vegetation on the permafrost carbon feedback. Simulations were conducted at a 1km resolution, over a 2,500 km2 area (50x50km square) centered on two long term ecological research sites in Alaska: Eight Mile Lake located in Interior Alaska (63.8900° N, 149.2535° W), and Toolik Field Station located on the northern foothills of the Brooks range (68.6500° N, 149.5800° W). Historical simulations are spanning the 1950 to 2015, and forced using climate simulations from the Climate Research Unit, time series 4.0. Future simulations are spanning 2016 to 2100, and forced using atmospheric CO2 emission scenario Representative Concentration Pathway (RCP) 8.5 and climate simulations from the Coupled Model Intercomparison Project Phase 5 (CMIP5) for two global circulation models: the Meteorological Research Institute (MRI) and National Center for Atmospheric Research (NCAR). The variables that are produced are gross primary productivity (GPP, in gC.m-2.y-1), net primary productivity (NPP, in gC.m-2.y-1), Heterotrophic respiration (RH in gC/m2/y-1), and active layer depth (ALD, m). The data are stored in netcdf files, the projection of used is NAD83/Alaska alders conical equal area (EPSG 3888).本数据集包含基于生物圈模型动态植被模型-动态有机土壤陆地生态系统模型（Dynamic Vegetation Model Dynamic Organic Soil Terrestrial Ecosystem Model, DVM-DOS-TEM）开展的模型模拟结果，该模型旨在表征植被深层氮获取对多年冻土碳反馈的影响。模拟以1km空间分辨率开展，覆盖面积为2500平方千米（50km×50km正方形区域），选取阿拉斯加的两个长期生态研究站点作为模拟中心：分别为位于阿拉斯加内陆的八英里湖站点（63.8900°N，149.2535°W），以及布鲁克斯山脉北麓的图利克野外站（68.6500°N，149.5800°W）。历史模拟时段为1950年至2015年，驱动数据采用气候研究单位（Climate Research Unit）4.0版时间序列的气候模拟结果；未来模拟时段为2016年至2100年，驱动数据采用典型浓度路径（Representative Concentration Pathway, RCP）8.5的大气CO₂排放情景，以及耦合模式比较计划第五阶段（Coupled Model Intercomparison Project Phase 5, CMIP5）下两个全球环流模式的气候模拟结果：分别为气象研究所（Meteorological Research Institute, MRI）与美国国家大气研究中心（National Center for Atmospheric Research, NCAR）的模式输出。本次模拟生成的变量包括总初级生产力（Gross Primary Productivity, GPP，单位：gC·m⁻²·y⁻¹）、净初级生产力（Net Primary Productivity, NPP，单位：gC·m⁻²·y⁻¹）、异养呼吸（Heterotrophic Respiration, RH，单位：gC·m⁻²·y⁻¹）以及活动层厚度（Active Layer Depth, ALD，单位：m）。数据以NetCDF格式存储，所用投影为NAD83/阿拉斯加阿尔伯斯圆锥等面积投影（EPSG 3888）。
