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., 2024. Mapping three-dimensional soil organic carbon density by soil depth function and correction methods in Yangtze River Delta, China. (In progress) Journal_TBD, DOI: XXXX

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)
