A China-wide dataset of soil hydraulic parameters derived from multiple pedotransfer functions for land surface modeling. The data includes parameters for the Clapp and Hornberger and van Genuchten and Mualem functions, plus water content at specific pressures, with median and coefficient of variation provided. Its vertical variation is captured across seven layers down to a depth of 1.38 meters.
Use Cases
- Calibrating land surface models based on soil hydraulic parameters for the Clapp and Hornberger functions.
- Simulating soil moisture dynamics based on parameters for the van Genuchten and Mualem functions.
- Assessing spatial variability in soil properties based on the provided coefficient of variation (CV) values.
- Modeling vertical water transport in soil profiles based on the seven-layer depth structure.
Strengths
- Provides parameters for two major soil hydraulic function families (FCH and FGM).
- Captures vertical soil property variation across seven distinct layers to a depth of 1.38 meters.
- Includes statistical measures (median and coefficient of variation) for parameter estimates.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
