The age distribution of global soil carbon inferred from radiocarbon measurements

We use 789 radiocarbon (∆¹⁴C) profiles, along with other geospatial information, to create globally-gridded datasets of mineral soil ∆¹⁴C and mean age. The spatial resolution is 0.5 degree by 0.5 degree and the vertical resolution is at each 1 cm increment to a soil depth of 1 meter.本研究利用789份放射性碳（radiocarbon，Δ¹⁴C）剖面数据，结合其他地理空间信息，构建了全球格网化的矿质土壤Δ¹⁴C及土壤平均年龄数据集。该数据集的空间分辨率为0.5°×0.5°，垂直分辨率以1cm为间隔，覆盖至1米深度的土壤剖面。
