Australian Soil Water Content Maps at Six Depths, 90m Resolution

18 modelled raster maps estimate the Drained Upper Limit Volumetric Water Content of Australian soils at six standard depths from 0-200cm. The data has a spatial resolution of 3 arc seconds (~90 meters) and represents conditions from approximately 1950 to 2021. Produced by the Soil and Landscape Grid of Australia, the maps follow GlobalSoilMap specifications and are provided in Cloud Optimised GeoTIFF format.

Use Cases

• Modelling agricultural water availability based on soil water content estimates.
• Assessing soil water storage capacity for environmental planning across different depths.
• Validating regional hydrological models using spatially continuous soil property data.

Strengths

• Provides data for six standardized depth intervals consistent with GlobalSoilMap specifications.
• Each of the 18 map layers contains approximately 2.007 billion pixels (49200 x 40800).
• Includes upper and lower confidence limits for each depth layer, aiding uncertainty assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is a modelled estimate, not direct measurement, which may introduce bias.
• Row count is unknown, which may limit suitability assessment for some analyses.
