Global maximum carboxylation rate trait scaling in the Sheffield Dynamic Global Vegetation Model 1901-2012

This data package contains model output data and climate input data associated with the New Phytologist publication: Walker, A.P., Quaife, T., van Bodegom, P.M., De Kauwe, M.G., Keenan, T.F., Joiner, J., Lomas, M.R., MacBean, N., Xu, C., Yang, X., Woodward, F.I., 2017. The impact of alternative trait-scaling hypotheses for the maximum photosynthetic carboxylation rate (Vcmax) on global gross primary production. New Phytologist 215, 1370–1386. https://doi.org/10.1111/nph.14623. This dataset contains maximum carboxylation rate at 25 ºC (Vcmax,25), Gross Primary Production (GPP), Net Biome Production (NBP), vegetation carbon, and soil carbon data from Sheffield Dynamic Global Vegetation Model (SDGVM) for multiple trait-scaling methods for scaling Vcmax,25 across Earth, and alternative instantaneous temperature scaling functions. Vcmax,25 values are mean top-leaf values taken during the growing seasons, which were defined as periods during which leaf area index (LAI) was greater than one. Vcmax,25 values were reported prior to scaling of Vcmax by water-stress or leaf-age.The attached metadata file (SDGVM_vcmax_dataset.docx) describes the methods used and explains the organization of data within the included .zip file. This metadata file is also included in PDF format. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: Funding for NGEE-Tropics data resources was provided by the U.S. Department of Energy Office of Science, Office of Biological and Environmental Research.

本数据包包含与发表于《新植物学家（New Phytologist）》的学术论文相关的模型输出数据与气候输入数据，论文详细信息如下：Walker, A.P., Quaife, T., van Bodegom, P.M., De Kauwe, M.G., Keenan, T.F., Joiner, J., Lomas, M.R., MacBean, N., Xu, C., Yang, X., Woodward, F.I., 2017. 《替代性状尺度假设对全球总初级生产力中最大光合羧化速率(Vcmax)的影响》，《新植物学家（New Phytologist）》215卷，1370–1386页，DOI: 10.1111/nph.14623。本数据集涵盖谢菲尔德动态全球植被模型（Sheffield Dynamic Global Vegetation Model, SDGVM）的多组输出数据，包括25℃下的最大羧化速率（Vcmax,25）、总初级生产力（Gross Primary Production, GPP）、净生物群系生产力（Net Biome Production, NBP）、植被碳与土壤碳数据，包含用于全球尺度下Vcmax,25缩放的多种性状尺度方法，以及不同的瞬时温度尺度函数。本次数据集的Vcmax,25值为生长季内顶部叶片的平均数值，其中生长季被定义为叶面积指数（Leaf Area Index, LAI）大于1的时段；所有Vcmax,25值均为未经过水分胁迫或叶龄校正的Vcmax缩放前的原始结果。附带的元数据文件（SDGVM_vcmax_dataset.docx）详细说明了所用研究方法，并阐释了压缩包内数据的组织架构，该元数据文件同时提供PDF格式版本。本数据集最初发布于NGEE Tropics Archive，现由ESS-DIVE进行镜像存档以实现长期归档。致谢：NGEE-Tropics数据资源的资助由美国能源部科学办公室生物与环境研究局提供。
