ORNL soil dataset 10k resolution:

The "Global Gridded Surfaces of Selected Soil Characteristics (IGBP-DIS)" data set contains 7data surfaces: soil-carbon density, total nitrogen density, field capacity, wilting point, profileavailable water capacity, thermal capacity, and bulk density.

These data surfaces were generated by the SoilData System, which was developed by the GlobalSoil Data Task Group of the International Geosphere-Biosphere Programme (IGBP) Data andInformation System (DIS). The SoilData System generates soil information and maps forgeographic regions at soil depths and resolutions selected by the user. Derived surfaces ofselected soil characteristics are suitable for modeling and inventory purposes. 

ISRIC soil dataset 1k resolution:

SoilGrids1km is a collection of updatable soil property andclass maps of the world at relatively coarse resolution of1 km. This is the output data-component of GSIF. Thepredictions are generated using automated soil mapping withno user intervention, and can therefore be regularly updatedas the new soil samples arrive. 

These datasets weer windoewed to E4warning study area

橡树岭国家实验室（Oak Ridge National Laboratory, ORNL）10k分辨率土壤数据集：
《全球网格化典型土壤属性表面数据集（IGBP-DIS）》包含7类数据表面：土壤碳密度、总氮密度、田间持水量、萎蔫系数、剖面有效持水量、热容量及容重。
此类数据表面由土壤数据系统（SoilData System）生成，该系统由国际地圈生物圈计划（International Geosphere-Biosphere Programme, IGBP）数据与信息系统（DIS）的全球土壤数据工作组研发。土壤数据系统可根据用户选定的土壤深度与分辨率，为地理区域生成土壤信息与专题地图。经推导得到的典型土壤属性数据表面可用于建模与土壤清单编制工作。

国际土壤参考与信息中心（International Soil Reference and Information Centre, ISRIC）1k分辨率土壤数据集：
SoilGrids1km是一套可更新的全球土壤属性与分类地图集，空间分辨率为相对粗粒度的1公里。该数据集为全球土壤信息设施（Global Soil Information Facility, GSIF）的输出数据组件。其预测结果通过全自动土壤制图生成，无需用户干预，因此可在获取新土壤样本时定期更新。
本数据集已被裁剪至E4预警研究区域范围内。
