Global soil mineral associated organic carbon saturation maps at 1 km resolution

We produced the global distribution of mineral associated organic carbon (MAOC), maximum MAOC, MAOC deficit, and percent MAOC saturation at 1 km resolution. The global map for MAOC was originally derived from Georgiou et al. (2022) and resampled to 1 km.This dataset (in TIFF) is associated to the "Global grasslands hold the largest unrealized potential for mineral-associated carbon sequestration" by Chen et al. (2025) and Georgiou et al. (2022).Manuscript citation: (1) Chen, S., Zhao, J., Minasny, B., Zhou, Z., Ren, C., Setia, R., Biswas, A., Chen, Z., Luo, Z., Shi, Z. , 2025.
