Global Climatic Soil Water Content and Consecutive Dry Days at 0.1° Resolution

A global raster dataset of climatic soil water content and consecutive dry days, calculated from precipitation, evapotranspiration, and soil data. The maps are generated at a 0.1° resolution with a global extent from -180 to 180 °E and -60 to 90 °N. It was created by Samuel Bickel of ETH Zurich using data from MSWEP, WorldClim, and SoilGrids.

Use Cases

• Modeling soil moisture dynamics based on climatic water content.
• Analyzing drought risk and water stress based on consecutive dry days.
• Studying global biogeography patterns of soil microbes based on environmental covariates.
• Validating hydrological and climate models using gridded global soil water data.

Strengths

• High spatial resolution of 0.1° for global analysis.
• Global spatial coverage from -180 to 180 °E and -60 to 90 °N.
• Derived from established data sources: MSWEP precipitation, WorldClim climate, and SoilGrids soil information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
