Data description This dataset is associated with the paper "Biotic and abiotic factors controlling spatial variation of mean carbon turnover time in forest soil". This dataset includes the soil organic carbon turnover time (τ soc ) based on radiocarbon signals at the global and regional scales. Global synthesis The analysis of global soil radiocarbon data was done using the International Soil Radiocarbon Database (ISRaD v.1.0; Lawrence et al., 2020). ISRaD is an open source data with the records of 8 biomes ( i.e., forest, grassland, cropland, shrubland, savanna, tundra, permafrost, and others). Since we focus on the turnover time of SOC (τ soc ) based on radiocarbon occurring in the natural forest ecosystem, so we limited our study to data from soil depth within 200 cm in the forest ecosystem. We built a database of radiocarbon-based soil turnover time (τ soc ) of 1897 soil samples from 245 forest locations worldwide. It covers a wide geographical range (35.65 o S ‒ 68.8 o N; 159.64 °W – 173.57 °E) and a ...
