A national soil organic carbon density dataset (2010-2024) in China using ensemble modelling based pedotransfer functions
收藏资源简介：
We present Version 10 (V10) of the China Soil Organic Carbon Stock (SOCS) Database, a national-scale dataset derived from 23,103 rigorously validated soil samples (7,995 profiles) using ensemble pedotransfer function (PTF) modeling.After re-validation and correction of profile statistics in the original files, the total number of profiles decreased to 7,995.The final V10 dataset provides standardized soil profile information, environmental covariates, and metadata, ensuring consistency and application-readiness. This dataset supports the manuscript:Chen et al. (2025). A national soil organic carbon density dataset (2010–2024) in China using ensemble modelling based pedotransfer functions. Users must cite both the repository (https://doi.org/10.1038/s41597-025-05863-3) and the above publication.Technical inquiries should be directed to Dr. Songchao Chen (chensongchao@zju.edu.cn). 2. Relationship Between Versions - V8: Developmental dataset including field observations and model predictions, used for training ensemble algorithms. Code is available on GitHub.- V9: The first finalized dataset, harmonized and validated for end-users.- V10: Updated, quality-checked dataset with unified metadata structure, improved variable naming consistency, and expanded coverage of sampling years (2010–2024). V10 supersedes V9 for applications. Each version is independent:- V8 supports reproducibility of modeling.- V9 was the initial application-ready dataset.- V10 is the latest standardized dataset for end-users.
