Global Soil Properties for Earth System Models

GSDE provides harmonized soil data, including particle-size distribution and organic carbon, at a 30 arc-second resolution globally. The dataset integrates the Soil Map of the World and regional databases using standardized taxotransfer rules and polygon linkage methods. It was developed by SCIOPS for use in Earth System Models.

Use Cases

• Model soil carbon sequestration dynamics using the organic carbon data across eight depth layers.
• Predict soil erosion risk by analyzing the spatial distribution of soil particle-size distribution attributes.
• Calibrate hydrological models using the area-weighted soil property data aggregated to lower resolutions.
• Assess regional soil nutrient availability for crop yield projections using the derived nutrient information.
• Validate satellite-derived soil moisture products against the gridded soil attribute confidence levels.

Strengths

• Data harmonized from multiple authoritative sources including the Soil Map of the World.
• Provides vertical soil property variation across eight layers down to a depth of 2.3 meters.
• Gridded at a 30 arc-second resolution, approximately 1 km at the equator.

Limitations

• Specific row count, column count, and temporal coverage are not provided.
• The dataset's derivation relies on linkage methods which may introduce aggregation errors.
• License and last update information are unknown.
