Global 1-km Gridded Thickness of Soil, Regolith, and Sedimentary Deposit Layers

This data set provides high-resolution estimates of the thickness of the permeable layers above bedrock (soil, regolith, and sedimentary deposits) within a global 30-arcsecond (~1-km) grid using the best available data for topography, climate, and geology as input. These data are modeled to represent estimated thicknesses by landform type for the geological present.本数据集基于地形、气候和地质的最佳可用数据，提供全球30弧秒（约1公里）分辨率下基岩（土壤、风化层和沉积物）上渗透层厚度的精细估算。这些数据通过地形类型建模，以体现地质现时的估算厚度。
