Global Data Set of Derived Soil Properties, 0.5-Degree Grid (ISRIC-WISE)

The World Inventory of Soil Emission Potentials (WISE) database was used to generate a series of uniform data sets of derived soil properties for each of the 106 soil units considered in the Soil Map of the World. These data sets were then used to generate GIS raster image files for the following variables: total available water capacity (mm water per 1 m soil depth); soil organic carbon density (kg C/m**2 for 0-30cm depth range); soil organic carbon density (kg C/m**2 for 0-100cm depth range); soil carbonate carbon density (kg C/m**2 for 0-100cm depth range); soil pH (0-30 cm depth range); and soil pH (30-100 cm depth range).

世界土壤排放潜力数据库（WISE）被用于生成一系列均质化的土壤衍生属性数据集，涵盖世界土壤图中的106个土壤单元。随后，这些数据集被用于生成以下变量的地理信息系统栅格图像文件：总有效水分容量（每1米土壤深度含水量，单位为毫米）；土壤有机碳密度（0-30厘米深度范围内的碳密度，单位为千克碳每平方米）；土壤有机碳密度（0-100厘米深度范围内的碳密度，单位为千克碳每平方米）；土壤碳酸盐碳密度（0-100厘米深度范围内的碳密度，单位为千克碳每平方米）；土壤pH值（0-30厘米深度范围内）；以及土壤pH值（30-100厘米深度范围内）。
