Three-dimensional soil organic carbon density by logarithmic function and coefficient scaling in Yangtze River Delta, China

Three-dimensional soil organic carbon density (SOCD) dataset with 90-m resolution generated by Lin, S., Zhu, Q., Yin, B., Yang, G., Liao, K., Lai, X., Guo, C., 2025. Generating three-dimensional soil organic carbon density dataset by soil depth function and correction methods in Yangtze River Delta, China. Environmental Modelling & Software, https://doi.org/10.1016/j.envsoft.2025.106582. Here, based on the best performance, the three-dimensional SOCD generated by LF corrected with coefficient scaling method were provided. The accurate SOCD maps with the spatial resolution of 90-m at any specific depth interval can be generated by our method. This dataset includes: Spatial distribution map of parameter 1 (p1) of LF (LF_p1.tif) Spatial distribution map of parameter 2 (p2) of LF (LF_p2.tif) The calculation code and fitted functions of scaling coefficient a, k of LF (fitted_fx_scalingcoff.m) Readme.docx Note: the unit of SOCD is kg m-2; the spatial distribution maps provided by this dataset does not mask any water bodies. How to use our dataset? Please refer to our article and Readme.docx for more details.
