Global temperature sensitivity of soil respiration (Q<sub>10</sub>) product from 1992 to 2018 at 5cm soil depth and from 1995 to 2018 at 10cm soil depth
收藏资源简介:
This code is for generating the soil respiration temperature sensitivity (Q<sub>10</sub>) product (unitless) from 1992 to 2018 at 5cm soil depth and from 1995 to 2018 at 10cm soil depth. Estimates were predicted using field observations and environmental variables with random forest models at global scale.The Q<sub>10</sub> products are at a 0.05 degree spatial resolution and yearly intervals.To save space, Q<sub>10</sub> products are compressed to zip files, and can be unziped using the software following https://www.wikihow.com/Unzip-a-File.The R code is provided to reproduce the study (files with ".R"), including the code to produce Q<sub>10</sub> maps and other analysis (e.g. trend analysis, SHAP analysis).We also provide the dataset of Q<sub>10</sub> field observations in global terrestrial ecosystems, which were collected from published literatures (“full.dat.csv”).
本代码用于生成1992年至2018年5cm土壤深度、1995年至2018年10cm土壤深度的土壤呼吸温度敏感性(Q₁₀,无单位)数据集。估算值基于全球尺度的野外观测数据与环境变量,通过随机森林(random forest)模型预测得到。该Q₁₀数据集的空间分辨率为0.05度,时间分辨率为年际间隔。为节省存储空间,Q₁₀数据集已压缩为zip压缩包,可按照https://www.wikihow.com/Unzip-a-File 中的步骤完成解压。本研究提供了可复现实验的R代码(后缀为".R"的文件),其中包含生成Q₁₀分布图的代码以及趋势分析、SHAP分析等其他分析代码。此外,数据集还包含从已发表文献中收集的全球陆地生态系统Q₁₀野外观测数据集,该数据集存储于"full.dat.csv"文件中。
