Soil organic carbon data with a 1 km × 1 km resolution were collected and derived from the Second Soil Investigation in China.
A conterminous China multi-layer soil particle-size distribution (sand, silt and clay content) dataset with a 1 km × 1 km resolution was developed according to the 1:1,000,000 scale soil map of China and 8595 soil profiles from the Second National Soil Survey (Wei et al., 2012).
